Sulphuric acid used in Lead Storage battery has a concentration of \(4.5 \mathrm{~M}\) and a density of \(1.28 \mathrm{~g} / \mathrm{~ml}\). The molality of the acid is __________.
- A 3.516
- B 4.012
- C 5.364
- D 2.568
Answer & Solution
Correct Answer
(C) 5.364
Step-by-step Solution
Detailed explanation
Given molarity \(M = 4.5 \text{ mol/L}\) and density \(d = 1.28 \text{ g/mL}\). The mass of \(1 \text{ L}\) of solution is \(1000 \text{ mL} \times 1.28 \text{ g/mL} = 1280 \text{ g}\). The mass of solute (\(H_{2}SO_{4}\)) in \(1 \text{ L}\) of solution is…
