Question

Don't need work just answers label answer with questions so I know 

At 100.0°C the molar heat of vaporization of water is 40.67 kJ/mol.
At 25.0°C, approximately room temperature, the molar heat of vaporization of water is 44.0 kJ/mol.
During a strenuous workout, an athlete generates 2210 kJ of heat energy. What mass of water would have to
evaporate from the athlete's skin to dissipate 2210kJ of heat?
