the mass of thr aspirin is on the first page.

Answer 1

c-eth to -e-oy ce O Caspirin salicylic acid. acetic autsy driche cheron OH Catho Oy & crcook equation : GheOg & Cythe Salicylic a molar mass of salicylie aid asiguin arid & C7 Hp02 (7x12 + 6 + 3x16) – 138 gmott molar mass of aspirin – - - Cq Hg Oy (9x12 + 8 + 4x16) 180g molt I mole salicylic acid 138 gmot salicylic acid so, 2 g of salicylic acid will gives I wole of aspirin produes 180 gmolt aspisin give 18ognol 82g 138gmor = 2.60 g as pirin

So manimum theoretical yield of aspirin is 2.609.) mass of aspirin = mass of watch glass and aspirin product - mass of a watch glass) = (57.259 - 55.3139) = 1.9379 I s. yield of aspirin = actual yield x 2007. theoretical gield 1.9379 x 1001 2.609 = 74.5 7. 1. Aspirin 1 actual product in each tablet - 325 mg wees - 0.325g yield = 1.9379 So, wo. of tablets which can be prepared 1.9379 a 5.96 tablets 0.3259 are ,
