MCQ - 257-2443

Question:

The density (in g mL^–1) of a 3.60 M sulphuric acid solution that is 29% H₂SO₄ (Molar mass = 98 g mol^–1) by mass will be:

1.45
1.64
1.88
1.64

Correct Answer: D

Explanation:

The relation between Molarity, M and mass percent (%) is given by:
M = (% x 10 x d) / MW
Where: MW = molecular weight of solute
d = density of solution Therefore:
d = M x MW / (% x 10) = 3.60 x 98 / 29 x 10 = 1.216 g mL^–1
