Question

The volume of 96% H2SO4 (density 1.83gmL−1) required to prepare 2.0L of 3.0M H2SO4 solution is

Answer 1

Here, 96 g sulphuric acid is present in 100 g of solution (96% by weight). Hence, 960 g sulphuric acid is present in 1 liter solution. Therefore, molarity of the solution will be 960/98.08 = 9.78 M. To prepare 2 liter of 3 M solution, you will need (3/9.78)*2000 = 613.5 ml of sulphuric acid and the rest will be water.
