Question

When 8.87 g of KOH are dissolved in 100.0 g of water in a calorimeter, the temperature increases from 25.0°C to 45.0°C. Use this information to determine the enthalpy change for the dissolution process in units of kJ/mol. Assume the specific heat of the solution is the same as that of pure water (4.18 J/g·C°) and that the density of the solution is 1.00 g/mL.
