Answer
Mass per cent is a way of expressing a concentration or describing the component in a particular mixture. The solution composition can be expressed in mass percentage that depicts the mass of solute present in a given mass of solution. The quantity of solute is expressed in mass or by moles. For a solution, the mass per cent is described as the grams of solute per grams of solution, multiplied by 100 to get the percentage.
Concentration
Mass of sodium chloride (Solute) = 36gm Mass of water (solvent) = 100 gm
Mass of solution = 36+100
∴ Mass of solution = 136 gm
Concentration = (Mass of Solute / Mass of Solution) * 100
Concentration = (36/136) × 100
Concentration = 26.47%
Temperature
If temperature increases, solubility increases and if temperature decreases, solubility decreases.
It is possible to distinguish the particles of solute from those of solvent in a suspension, since particle size is bigger in suspensions, hence it is easier to distinguish the particles of solute.

Here,
- Solute is sodium chloride
- Solvent is water .
Now,
Mass of solute = Mass of sodium chloride = 36g
Mass of solvent = Mass of water = 100g
Mass of solution = Mass of solute + Mass of solvent
= 36g + 100g
= 136g
Concentration of solution = (Mass of solute (g)/Mass of solution(g)) × 100%
= (36/136) × 100%
= 9 × 100/34 %
= 26.47 %
