Post Laboratory Questions 1. When pure sulfuric acid dissolves in water, a great deal of heat is liberated. To determine the enthalpy of solution, 175 g of water was placed in an open calorimeter and cooled to 20.0°C. Then 5.00 g of pure, concentrated sulfuric acid, H2SO4(1), also at 20.0°C, was added and mixed in. The temperature rose rapidly to 25.4°C. Assume that the specific heat of the solution is 4.184 JgC¹. Ccal = 19 J/°C. Calculate q. Then, calculate the AH of solution for one mole of H2SO4.
