Question

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.​

Answer 1

Answer:

%mass/mass=mass of solute/mass of solution ×(100)

mass of solute=40gm

mass of solvent=320gm

mass of solution=360gm

by the formula,

40/360×(100)=

100/9%

=11.11...% (answer)

Answer 2

Answer:

Explanation:

Mass of solute- 40g

Mass of solution - 360 g

Concerntration mass by mass-

40g÷360g×100=11.1
