38% (w/w) Sulphuric acid with density of 1.3g/mL is used in acid storage battery. If 50% of the entire available sulphuric acid from the battery containing 1L of the acid is consumed, the number of Faraday of electrical charge that can be drawn is

2.52 FaradayMass of 1 L of Sulphuric acid = 1.3 x 1000 = 1300 gMass of  Sulphuric acid in it = 1300 x 0.38 = 494 gMass of Sulphuric acid consumed = 494 x 0.5 = 247 gNo.of mole of Sulphuric acid consumed = 24798 = 2.52 mole2.52 mole of Sulphuric acid consumed will make 2.52 Faraday of electrical charge to flow through the external circuit.
