THANKS FOR QUESTION

YOUR ANSWER IS

Mass of solute = 36 g.

Mass of solvent = 100g.

Mass of solution = 100 + 36.

= 136g.

Concentration of solution = (Mass of solute / Mass of solution ) x100.

= (36/136) x 100.

= 26.47%

(b) If temperature increases, solubility increases and if temperature decreases, solubility decreases.
