Tooooo much chemistry for us.

We don't know relevant chemistry formulas.

Sorry.

But if you have this knowledge, this lesson might be of help to you

One mole of salicylic acid plus enough acetic anhydride could produce one mole of acetylsalicylic acid (aka aspirin).
Their molar masses are 138.12 and 180.16 g%2Fmol , so the ratio of masses of aspirin to salicylic acid will be 180.16%2F138.12 .
That means that 2.345g of salicylic acid could produce
%282.345g%29%2A%28180.16%2F138.12%29=highlight%283.059g%29 of aspirin.

NOTES:
Since the mass of salicylic acid was given with 4 significant digits,
giving the answer with 4 significant digits makes science sense.

For chemistry problems, there is a website called yeahchemistry.
I used to answer questions there years ago, but the need for help was much greater here.
I believe the ratio of tutors to questions there is still much better than here, and they all know chemistry.
