Question

Density of 98 sulphuric acid is 1.84g cm3 at 20 celsius. Calculate molality

Answer 1

Hey mate here's your answer

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.
