Three liquid samples of known masses are heated to their boiling points with the use of a heater rated at 500.0 W. Once the boiling points of each sample are reached, the samples are heated for an additional 4.96 min, which results in the vaporization of some of each sample. After 4.96 min, the samples are cooled and the masses of the remaining liquids are determined. The process is performed at constant pressure. The results are recorded in the table. Liquid CH₂OH Boiling point (°C) 64.5 C4H10 -1.00 C6H6 80.1 Initial mass (g) Final mass (g) 465.2 340.37 496.1 95.69 683.6 339.68 Calculate the molar enthalpy of vaporization, AHvap, and the molar entropy of vaporization, ASvap, for each sample.
