Question

Calculate the volume of 80% (by mass) of H2SO4 (density = 1.80g/ml) required to prepare 1 litre of 0.2 molar H2SO4.
​

Answer 1

Density of 80% sulphuric acid would be 1.8 g/ml not 1.8g/mol. First you have to calculate the molarity of 80% acid solution which will act as stock solution. In next step you require 0.2 M acid solution from 14.68M stock solution. 13.62 ml of 80 % sulphuric acid is required.A
