| Enthalpy |
Use standard enthalpies of formation to calculate the standard change in enthalpy for the melting of ice. (The ΔH˚f for H2O(s) is –291.8 kJ/mol.) Use this value to calculate the mass of ice required to cool 360 mL of a beverage from room temperature (25.0˚C) to 0.0˚C. Assume that the specific heat capacity and density of the beverage are the same as those of water.
