How do I calculate this??!!

1. If you use 3.50g of salicylic acid, how much acetyl salicylic acid should you make?

2. If you synthesized 1.82g, what is your percent yield?

a. the question didn't come out right. For each mole of salicytic acid, you should make one mole of aspirin. convert to moles, then back again, and you have it.

I don't know that is the question that the professor give me. That is all the information in both questions.

To calculate the amount of acetyl salicylic acid (ASA) you can make from 3.50g of salicylic acid, you need to know the balanced equation for the reaction between salicylic acid and acetic anhydride. Let's assume the equation is:

Salicylic acid + Acetic anhydride -> Acetyl salicylic acid + Acetic acid

Next, determine the molar masses of salicylic acid and acetyl salicylic acid. The molar mass of salicylic acid is 138.12 g/mol, while the molar mass of acetyl salicylic acid is 180.16 g/mol.

Now, you can use the molar ratio between salicylic acid and acetyl salicylic acid to calculate the amount of acetyl salicylic acid produced:

(3.50g Salicylic acid) x (1 mol SA/138.12 g SA) x (1 mol ASA/1 mol SA) x (180.16 g ASA/1 mol ASA) = amount of ASA produced

To calculate the percent yield, compare the actual yield (1.82g) to the theoretical yield (the amount of ASA calculated in the previous step). The formula for percent yield is:

Percent yield = (actual yield/theoretical yield) x 100%

Substituting in the values:

Percent yield = (1.82g/amount of ASA produced) x 100%
