How many moles are in 1.25 x 1021 molecules of sucrose?
How many moles of aspartame are present in 197 g of aspartame, C14H18N2O5?
Answers
A mole is 6.022 x 10²³ of any chemical unit, including atoms, molecules, ions, and others.
Given information,
Number of molecules of sucrose = 1.25 x 10²¹
Mass of aspartame = 197 g
(a) The number of moles in sucrose = Number of molecules/Avagadro number
The number of moles in sucrose = 1.25 x 10²¹/6.022 x 10²³ = 0.00208 moles
(b) The molar mass of Aspartame = (14 x 12.011) + (18 x 1.008) + (2 x 14.007) + (5 x 15.999) = 294.3 g/mol
Number of moles = Mass/molar mass = 197/294.3 = 0.669 moles
Therefore, the number of moles in sucrose is 0.00208, and in aspartame is 0.669.

There is a coarse and boisterous money-making fellow in the outskirts of our town, who is going to build a bank-wall under the hill along the edge of his meadow. The powers have put this into his head to keep him out of mischief, and he wishes me to spend three weeks digging there with him. The result will be that he will perhaps get some more money to board, and leave for his heirs to spend foolishly. If I do this, most will commend me as an industrious and hard-working man; but if I choose to devote myself to certain labors which yield more real profit, though but little money, they may be inclined to look on me as an idler. Nevertheless, as I do not need the police of meaningless labor to regulate me, and do not see anything absolutely praiseworthy in this fellow’s undertaking any more than in many an enterprise of our own or foreign governments, however amusing it may be to him or them, I prefer to finish my education at a different school.

D add to the positive, optimistic mood
Answers
In the context of the poem "There But for the Grace," the words "rain," "shadow," and "sunny weather" in lines 10-11 do not convey an upbeat, jaunty tone or add to a positive, optimistic mood. Instead, they relate to good times and hard times, reflecting the contrasting experiences and circumstances in life.The correct answer is option A.
The poem explores the concept of empathy and reminds the reader that their own fortune could easily have been different if not for the grace or luck they have received.
The mention of rain and shadow suggests difficult and challenging times, symbolizing hardships and struggles. These elements represent the darker aspects of life that everyone encounters at some point.
On the other hand, the reference to sunny weather symbolizes the good times, happiness, and positive experiences. These opposing images of rain, shadow, and sunny weather highlight the dichotomy between the speaker's experiences and the potential experiences of others who have not been as fortunate.
Overall, these words contribute to the understanding that life is a mixture of both good and bad times, and they emphasize the importance of empathy and compassion towards others who may be going through challenging circumstances.

When is it a good idea to use expert testimony in a speech?
a) When presenting personal anecdotes
b) When appealing to emotions
c) When providing statistical data
d) When presenting authoritative opinions
Answers
Expert testimony is most commonly used when presenting authoritative opinions in a speech. Here option D is the correct answer.
Expert testimony is a powerful tool that can enhance the credibility and persuasiveness of a speech. It is particularly useful in situations where presenting authoritative opinions is necessary.
When addressing complex or technical subjects, expert testimony lends weight to the speaker's arguments and can help establish their expertise on the topic. This is especially important when attempting to convince an audience that may have limited knowledge or understanding of the subject matter.
Expert testimony is also valuable when providing statistical data. Experts can interpret and explain data in a way that is accessible to the audience, helping them grasp the significance and implications of the numbers. By referencing experts in the field, speakers can bolster the credibility of their data and increase its impact.
While personal anecdotes and emotional appeals can be compelling, expert testimony may not be as effective in those situations. Personal anecdotes rely on the speaker's own experiences, and emotions are best evoked through relatable stories or vivid language.
However, when it comes to presenting factual information, expert testimony is crucial for establishing credibility and providing solid evidence.

A 22 year old Gold Coast man has become the youngest Queenslander to be diagnosed with the dangerous disease, silicosis. What is the main cause of the disease?
a. Exposure to fine dust from cutting stone benchtops.
b. Regular use of weedkiller.
c. Exposure to dust from sanding back lead paint.

Silicosis is a disease that arises as a result of engaging in occupation which requires exposure to fine silica dust. This disease affects the lungs because the dust particles are inhaled. Symptoms associated with this disease include, cough, shortness of breath and discoloration of the skin. These symptoms are similar to those suffered by asthmatic patients.
Occupations that require stone cutting or even mining can lead to exposure to these diseases. Therefore, the 22 year old Gold Coast man who was affected by Silicosis was most likely involved in an occupation that exposed him to inhalation of fine silica dust.
