(a)
Interpretation: for the given reaction, the mass of salicylic acid required to produce 0.400g of aspirin, the mass of salicylic acid required to produce 0.400g of aspirin if the 74.9% salicylic acid is converted to aspirin and the percent yield of 10.9g of aspirin if 9.26g of salicylic acid reacts with 8.54g of acetic anhydride are needed to be determined.
Concept introduction:
- Balanced chemical equation of a reaction is written according to law of conservation of mass.
- Equation for Number of moles of a substance, from its given mass is,
- Percent yield of reaction is the ratio of mass of actual yield to the mass of theoretical yield and multiplied with hundred.
