Answer:
a.
A true solution is a homogeneous mixture with uniform properties throughout. In a true solution the solute cannot be isolated from the solution by filtration. The particle size of the solute is about the same as that of the solvent, and solvent and solute pass directly through the filter paper.
b.
Mass of solute= 16 g
Mass of solution =120g
Mass % = mass of solute ÷
mass of solution × 100
= 16 ÷ 120 × 100
=13.333333333...%
= 13 % (approx)
