Question

A battle of sulphuric acid(density = 1.6g/m is labelled as 86% by mass. What is the molarity of the solution? What volume of the acid is required to make 200 ml of 0.7 M H2SO4​

Answer 1

Explanation:

Molarity= 10 x Specific gravity x purity/ Molecular weight

Molarity = 10 x 1.6 g/mol x 86 / 98 = 14.04 M

M1V1= M2V2

14.04 M x V1 = 0.7 M x 200 mL

V1 = 0.7 M x 200 mL / 14.0 M = 10 mL
