Finding the percent yield for Aspirin

I am trying to figure out the theoretical yield for aspirin.. We measured out .138 grams of salicylic acid and after the crystallization I was left with 0.102g of Aspirin. Im not sure if im calculating this right..

.138g salicylic acid x (1mol salicylic acid/138g salicylic acid) (1mol/1mol) (138g salicylic acid/.102 aspirin)

grams salicylic acid => mol salicylic acid =>mol aspirin => grams aspirin

The molecular weight for Aspirin is 180.16 grams
