Determine the theoretical yield of aspirin in grams. Show all mathematical work

Question

Mass of aspirin 2.357g mass of salicylic acid 2.027g

Answer 1

Salicylic acid (SA) + acetic anhydride ==> aspirin + acetic acid

Theoretical yield of aspirin:

2.027 g SA x 1 mol SA/138 g x 1 mol aspirin/mol SA x 180 g aspirin/mol = 2.644 g aspirin

Percent yield:

actual yield/theoretical yield (x100%)

2.357 g/2.644 g (x100%) = 89.15% yield
