A student prepared aspirin (C9H8O4) in a laboratory experiment using the following reaction.

C7H6O3 + C4H6O3 C9H8O4 + HC2H3O2

The student reacted 2.00 g salicylic acid (C7H6O3) with 2.67 g acetic anhydride (C4H6O3). The yield was 2.00 g aspirin. Calculate the theoretical yield and the percent yield for this experiment.

the first one:

2.00g C7H6O3 x (mol C7H6O3/138.12g C7H6O3) x (molC9H8O4/mol C7H6O3) = .014

is this right??
and for the other one i got .026

i changed .014 mol to C9H8O4g as the theoretical

where did i go wrong??
