Question

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

Answer 1

Explanation:

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g

concentration of solution=Mass of solute/massofsolution ×100

40/360 × 100 = 11.11%

Hence, the concentration of the solution is 11.11%

Answer 2

Answer:

11.11%

Explanation:

mass of solute=40g

mass of solution =320g+40g

=360g

mass by mass% = 40/360 ×100

=11.11%
