Question

A solution contains 40 g of common salt dissolved in 320 ml of water.

Calculate the mass concentration of the solution​

Answer 1

Given:

Mass of common salt (solute) = 40 g

Mass of water (solvent) = 320 g

Solution:

Mass of solution = 320 + 40

= 360 g

Concentration of solution = (Mass of solute/Mass of solution)×100

= (40/360) x 100

= 11.11 % (approx.)
