If the solubility of sugar at 25ºC is 211 g/100 g H2O, what mass of sugar can be dissolved in 300 g of H2O?

633 g of Sugar

105.5 g of Sugar

422 g of Sugar

844 g of Sugar

Answers

Answer 1

Answer:

633 grams of sugar can be dissolved in 300 g of H₂O

Explanation:

Solubility is the measure of the ability of a certain substance to dissolve in another and form a homogeneous system. Solubility is then the maximum amount of a solute that a solvent can receive and is expressed by concentration units.

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

Then:

$x=\frac{c*b}{a}$

You can apply the rule of three as follows: if by definition of solubility in 100 grams of H₂O there are 211 grams of sugar, in 300 g of H₂O how much sugar is there?

$sugar=\frac{300 grams of H_{2}O *211 grams of sugar}{100 grams of H_{2}O}$

sugar= 633 grams

633 grams of sugar can be dissolved in 300 g of H₂O

Answer 2

Answer:

$X g\ sugar=633 g \ sugar$

Explanation:

Hello,

In this case, solubility is defined as a condition wherein the amount of a solute has been completely dissolved in a certain amount of solvent and it is temperature-dependent as well. In such a way, for the given solubility at 25 °C, we understand that 211 g of sugar are completely dissolved in 100 g of water, therefore, for 300 g of water, we can compute the completely dissolved mass of sugar by using the following rule of three:

$211g\ sugar \rightarrow 100 g \ water\\\\X g\ sugar \rightarrow 300 g\ water\\\\X g\ sugar =\frac{300g\ water * 211g\ sugar}{100g \ water}\\ \\X g\ sugar=633 g \ sugar$

Best regards.

What are the ways of biodiversity protection?

Captive breeding and habitat preservation are two important ways to protect biodiversity. Captive breeding involves the capture and breeding of endangered species in a controlled environment to increase their population size.

This method is used for species that are in danger of extinction in the wild due to factors such as habitat destruction, poaching, and disease. By breeding the species in captivity, the population can be increased and eventually released back into the wild to help restore the species' population.

Habitat preservation, on the other hand, involves protecting natural habitats from human activities such as logging, mining, and urban development.

By preserving habitats, the native species that rely on these habitats can continue to live and thrive, maintaining a healthy ecosystem. This is crucial for the conservation of biodiversity, as many species are dependent on specific habitats for their survival.

Hence, option b is correct.

What happens to air pressure and amount of oxygen as the altitude increases in Earth's atmosphere? 1. Air pressure decreases, while the amount of oxygen increases. 2. Both air pressure and the amount of oxygen increase. 3. Air pressure increases, while the oxygen decreases. 4. Both air and oxygen decrease.

Answers

Answer:

As altitude increases in Earth's atmosphere, both air pressure and the amount of oxygen decrease.

At sea level, the air pressure is about 1013.25 millibars (mb) and the concentration of oxygen is about 21%. As you go higher in the atmosphere, the air becomes thinner and less dense, so the air pressure decreases. At the same time, the concentration of oxygen also decreases because there is less air overall to contain oxygen molecules.

This is why it is harder to breathe at high altitudes, such as on a mountain. The air is less dense, so there are fewer oxygen molecules per breath and the body has to work harder to get enough oxygen.

Answer:4: Both Air and Oxygen decrease.

Explanation:This is in accordance with Henry's law. As pressure decreases solubility of gases decreases. Air pressure decreases as we altitude increases and the decrease in oxygen level is the consequence ,

D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL

Answers

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

the correct answer is A 4.8 mL

If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.

It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.

Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side

The number of carbon atoms on reactant side is 2 while on the product side it is 2

The number of Hydrogen atom on reactant side is 4 while on the product side it is also 4

The number of oxygen atom on reactant side is 1 while on the product side it is 6, so to balance oxygen we multiply O₂ by 3 so the balanced equation is

C₂H₄+3O₂$\rightarrow$2CO₂+2H₂O

Thus the balanced equation is C₂H₄+3O₂$\rightarrow$2CO₂+2H₂O. Option B is correct option

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.

Answers

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s
