Q:-
A regular dose of aspirin contains 325 mg of aspirin. How many aspirin tablets could be made from the aspirin prepared when 4g of salicylic acid was used with excess amount of acetic anhydride?
A:-
after balance equations they are one to one ratio so:
4g (C7H6O3) x 1mol salicylic acid (s.a)/138.07g s.a. x 1mol aspirin (as)/ 1 mol s.a x 180.07g as/ 1 mol as = 5.2174g of aspiring.
now divide the theorical yield over the regular dose of aspiring in a tablet, (dont forget to convert milligrams to grams) so: 5.2174g/0.325g= 16.0 tablets
