I am soo lost on this one, I don't even know where to begin! I have read the chapter and it's just not clicking!
If you start your reaction with 0.083 g of salicylic acid, what theoretical yield of acetylsalicylic acid would you predict?
If your experimental yield of acetylsalicylic acid is 0.094 g, what is the percent yield of your synthesis?

Write the equation. We can't draw structures on this forum but let's call salicylic acid SA, acetylsalicylic acid as ASA, and I know the reaction is 1:1. Therefore,
SA --> ASA
mols SA = grams SA/molar mass SA = ?
mols ASA = mols SA since it is 1:1
Then g ASA = mols ASA x molar mass ASA. This is the theoretical yield (TY).
The actual yield from the problem is 0.094 g (AY).
So % yield = (AY/TY)*100 = ?
