Molarity = moles of solute(CuSO4)/volume of solution(Liters)
0.967 grams CuSO4 (1 mole CuSO4/159.62 grams) = 0.00606 moles CuSO4
Molarity = 0.00606 moles/0.020 liters
= 0.303 Molarity

What is the residue when sodium chloride water solution was heated to dryness?
When a mixture of sodium chloride and water is heated to dryness, the residue is sodium chloride, because the boiling point of sodium chloride is much higher than the boiling point of water.
