WebSep 24, 2014 · The enthalpy change of solution or ΔH sol is the enthalpy change when 1 mole of a solute dissolves to form an "infinitely" dilute solution and can be measured experimentally. In this case it refers to: KN O3(s) + (aq) → KN O3(aq) We measure the strength of the ionic attractions in a lattice by the lattice enthalpy ΔH L. WebThe total mass of the solution is 1.50g + 35.0g = 36.5g. You should be multiplying 36.5g by the temperature change and heat capacity. Then, you need to consider how many moles 1.50g KCl is. Divide the change in enthalpy of the solution by the number of moles of KCl to determine the molar heat of solution of KCl.
