What is the enthalpy change when 5.0 g of NaOH dissolves in 100.0 mL of water at 25 °C? Assume that the specific heat capacity of the solution is equal to the specific heat capacity of water and that the heat capacity of the calorimeter is negligible. The molar mass of NaOH is 40.00 g/mol and the density of water is 1.00 g/mL. Use the following equation to calculate the enthalpy change:
ΔHsoln = qsoln/moles of solute
