When sulphuric acid dissolves in water, a great deal of heat is given off. The enthalpy change for this process is called the enthalpy of solution. To measure it, 175 g of water was placed in a coffee-cup calorimeter and chilled to 10oC. Then 49.0 g of pure sulphuric acid, also at 10.0oC was added, and the mixture was quickly stirred with a thermometer. The temperature rose rapidly to 14.9oC. Assume that the value of the specific heat of solution is 4.184 J/goC. You may assume that the specific heat of the resulting sulphuric acid solution will also be 4.184 J/goC. Calculate q for the formation of this solution, and calculate the enthalpy of solution in kilojoules per mole of H2SO4.
