Answer:
Weight of solute = 20 g
Weight of solvent = 80 g
Weight of solution = weight of solute + weight of solvent : (20 + 80)g = 100g
% w/w = mass of solute (or solvent)/ mass of solution x 100.
Of solute = 20/100 x 100% = 20%
And % of solvent = 80/100 x 100% =80%
Explanation:
Solute: 20%, Solvent: 80%.
