How many grams of 0Celcius ice can be converted into 0 Celcius liquid water by the addition of 100. kJ of heat energy? (ΔH°fus= 6.02 kJ/mol)

100kJ x 1molH2O/6.02kJ x 18gH2O/1molH2O = (100)(18)/(6.02) = 300g H2O

Let ice be called H2O. Atomic weights: H=1 O=16 H2O=18

L.H. of fusion of ice = 334 kJ/kg.
100 / 334 = 0.3kg grams of ice will melt at 0°C.
