1.

Calculate the molarity of 5% w/v H2SO4

Answer»

Density of solution d (1g/L)

volume of solution(water) V

mass of H2SO4dissolved = 1% of total mass of solution = 0.01dV

mass per litre of H2SO4 0.01dV/V = 0.01 * 1g/L

Molarity of solution = mass perlitre of H2SO4 dissolved / equivalent weight of H2SO4 = 0.01 * 1 / 49 = 0.0002 M
