Question

800ml of 40% of solution of sulphuric acid is prepared by adding concentrated H2SO4. How much sulphuric acid is added to water.

Answer 1

Answer:

Explanation:

Molecular weight of H2SO4 is 98.079 g-mol.

1 ml equals 1.84 g. Hence, 96 ml equals 96 x 1.84 = 176.64 g.

Therefore, 100 ml volume contains 176.64 g H2SO4. So 1 liter contains 1776.4 g.

Hence, the molarity is 1776.4/98.079 = 18.11 M.
