To make a saturated solution, 36 gm of sodium chloride is dissolved in 100 gm of water at 293 K. Find its concentration at this temperature.

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.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
