Calculate the amount of energy in kilojoules needed to change 423g of water ice at -10 deg c to steam at 125 deg c . The following constants may be useful:
* C(ice) = 36.57 ~J/(mol C)
* C(water) = 75.40 ~J/(mol C)
* C(steam) = 36.04 ~J/(mol C)
* Delta H{fus} = +6.01 {kJ/mol}
* Delta H{vap} = +40.67 {kJ/mol}
