Calculate the work done in joules when 1.0 mole of water vaporizes at 1.0 atm and 100°C. Assume that the volume of liquid water is negligible compared with that of steam at 100°C, and ideal gas behavior.

10 points for best answer!

Work = P.V

but, P.V = nRT
so Work = nRT

just put in the values. Use an appropriate R value though like 8.314 J/mol.K and T = 383K you can do the rest.
