Question

aspirin C6H4(CO2)(CO2CH3),can be prepared in the chemistry laboratory by the reactions of salicylic acid, C6H4(CO2H)(OH),with acetic anhydride(CH3CO)2O.what volume of acetic anhydride(density,1.0820g/cm3) is required to produce 1.00kg of aspirin, assuming a 100% yield

Answer 1

262mol 1=kg
g=1000
from stoichoimetry

x=102*1000/360
x=102000/360
x=283.33

density =m/v
=283.33/1.082
=262mol
