To calculate the molar heat of vaporization (J/mol) of water, you can use the equation:

Molar heat of vaporization (J/mol) = Heat of vaporization (J/g) / molar mass of water (g/mol)

The molar mass of water (H2O) is approximately 18.015 g/mol. Therefore:

Molar heat of vaporization (J/mol) = 2260 J/g / 18.015 g/mol = approximately 125.69 J/mol
