21.5 g of sodium chloride dissolves in 60 g of water at 25° C. Calculate the solubility of sodium chloride in water at that temperature.
Solubility of a solute=(Weight of solute in saturted solution)/(Weight of solvent in saturated solution)×100
Solubility of a solute=21.5/60×100
Solubility of a solute=35.833 g/100 mL of water
As water has a density 1 g/cc solubility is expressed as 35.833 g/100 mL of water.
