Aspirin (C9H8O4) is produced from salicylic acid (C7H6O3), and acetic anhydride (C4H6O3):
C7H6O3 + C4H6O3 Би C9H8O4 + HC2H3O2

How much salicylic acid is required to produce 2.0 102 kg of aspirin, assuming that all of the salicylic acid is converted to aspirin?

for this one i got1.5e2kg which i know is correct

How much salicylic acid would be required if only 87% of the salicylic acid is converted to aspirin?

for this one i just took my answer from number one and multiplied it by .87 but the answer was wrongl. what i am doing wrong?
