Question

A solution contains 55g of sodium chloride in 310g of water.  Calculate the concentration in terms of mass by mass percentage of the solution.​

Answer 1

Answer:

15.06%

Explanation:

mass by mass % concentration is calculated on the basis of the total mass.

so total mass of the solution = 310 + 55 = 365g

so concentration = 55/365 * 100 = 15.06%
