Question

Calculate the mass of ethanoic acid formed when jareds 18.0g of aspirin is hydrolysed

Molar mass of ethanoic acid =60.0gmol-1​

Answer 1

6 grams.

Step-by-step explanation:

The equation of the reaction is

C9H8O4 + H2O ----> CH3COOH + C7H6O3

1 mole of aspirin gives 1 mole of ethanoic acid.

Molar mass of aspirin = 180 gmol-1.

So the mass of ethanoic acid formed = 18/180 == 1/10 of a mole.

= 60 / 10 = 6 grams.
