Explanation:
Expert Answer:
(a) 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.

Answer:
Mass of solute (sodium chloride) = 36 g
Mass of solvent (water) = 100 g
Mass of solution
= Mass of solute + Mass of solvent
= 36 g + 100 g = 136 g
