Question

to make a saturated solution36 gram of sodium chloride is dissolvedin 100 gram of water at 293k find its concentration at this temperature.​

Answer 1

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.
