Ok, does anyone know how to calculate the energy absorbed to produce water vapor? I was given the molar head of vaporization for water which is 40.79 kj/mol, but i'm not sure wtf i'm supposed to do with it. Also, i need to calculate the total heat gained by water in the calorimeter which would be the heat gained of H2O(liquid) + heat gained of H20(gas). Calculating them would simply be using the q=mc*delta t but, how do i calculate the temperature of the water vapor? Thanks!
