Question

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

(a) 1.45 

(b) 1.64

(c) 1.88 

(d) 1.22

Answer 1

(d) : 3.6M solution means 3.6mole of H₂SO₄ is present in 1000ml of solution.
Therefore, Mass of 3.6moles of H₂SO₄ = 3.6 × 98g = 352.8g
