question

Calculate the work done when 18.0g of liquid water are vaporized at 100°C against a constant external pressure of 1.00 atm, given that \DeltaH_vap (H_2O) = 9.7 kcal mole^-1 \DeltaH_fus (H_2O)= 1.4 kcal mole^-1 R= 0.0820 liter atm mole^-1 deg^-1 = 1.99 cal mole^-1 deg^-1 Density of H_2O(l) = 1.00g cm^-3 and molecular wt of water = 18.0 g mol^-1
