1. A student determines the heat of dissolution of solid magnesium chloride using a coffee-cup calorimeter of negligible heat capacity. When 0.430 g of MgCl2(s) is dissolved in 118.00 g of water, the temperature of the solution increases from 25.00 to 26.54 °C. Based on the student's observation, calculate the enthalpy of dissolution of MgCl2(s) in kJ/mol. Assume the specific heat of the solution is 4.184 J/g°C. ___?
