What is the value of q when 8.29 g of water vaporizes at 373 K? The enthalpy of condensation of water at 373 K is -40.7 kJ/mol.

Question

Quizplus · Accepted Answer

The enthalpy of vaporization is the negative of the enthalpy of condensation. First, convert 8.29 g of water to moles (8.29 g / 18.015 g/mol = 0.460 moles). Then, multiply the moles by the enthalpy of vaporization (0.460 moles * 40.7 kJ/mol = 18.7 kJ).
