A solution contains 40 g of common salt ...

A solution contains 40 g of common salt in 320 g of water. Calculate the concentration in terms of mass by mass percentage of the solution.

Text Solution

Verified by Experts

Mass of solute (salt) = 40 g
Mass of solvent (water) = 320 g
Mass of solution
= Mass of solute + Mass of solvent
= 40g + 320g
= 360 g
Mass percentage of solution
= `("Mass of solute")/("Mass of solution")xx100`
= `40/360xx100`
= 11.1 %
