Question

A solution contains 40 g of common salt in 320 g of water at 293 K . Calculate the concentration in terms of mass by mass percentage of the solution

Answer 1

Answer:

11.11%

Explanation:

Mass of Solute = 40g

Mass of the Solvent = 320g

Now,

Mass of the solution = 320g + 40g

Then Concentration will be = Mass of the Solute/ Mass of the Solution

= 40/360 * 100 = 11.11%
