Hope it will help you.mark me as brainleast

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 2

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
