Problem based on mass percentage:-
  
 16 grams of NaOH is dissolved in 100 grams of water at 25°C to form a saturated solution. Find the mass percentage of solute and solvent.
 
Mass of the solute (NaOH) = g

Mass of the solvent (H2O) = g
 
i. Mass percentage of the solute:
  
Mass percentage of solute = / (Mass of the solute + ) x 100.
 
Mass percentage of solute = () / ().
 
Mass percentage of solute = 1600 / 116.
 
Mass percentage of the solute = %.
 
ii. Mass percentage of solvent = 100 - Mass percentage of the solute.
 
Mass percentage of solvent = 100 - 13.79.
 
Mass percentage of solvent = %.
