Question

to make a saturated solution 36g of sodium chloride is dissolved in 100th of water at 293k find it's concentration at this temperature ​

Answer 1

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

If temperature increases, solubility increases and if temperature decreases, solubility decreases.
