QUESTION 40 You are experimentally determining the enthalpy of solution for an ionic compound using a coffee cup calorimeter. When you dissolve 32.14 g of the ionic compound (molar mass - 138 g/mol) in 409 g water in a coffee cup calorimeter, the temperature changes from 21.74°C to 15.89 °C. Calculate the enthalpy of solution (the enthalpy change when dissolving the ionic compound in water) in /mol. Use 4,184 18°C) for the specific heat capacity of the solution. Give your...
