1. 24g salt is dissolved in 300 g solution. Calculate the concentration in terms of mass
by mass percentage of the solution.
2. 40 g salt is dissolved in
a solution having concentration 10 % w/w. Find the mass of solvent.

Answer:
1) % w/w = mass of solute÷mass of solution×100
=24÷300×100
=8g
2) same equation as above.
10 = 40÷ mass of solution × 100
=400g is the mass of solution.
therefore, 400= mass of solvent + 40
mass of solvent = 360g
