Question

In the experiment to measure latent heat of ice, you get the following data. What is the latent heat of ice in J/kg? (answer within +-3% will considered correct) (Since the numbers are chosen randomly, the answer may not represent the actual value of latent heat)

MASSES: water= 154 g,   ice=50 g,   calorimeter=62 g

INITIAL TEMPERATURES: water+calorimeter=28ºC, Ice=0ºC

Final equilibrium temp=18ºC

Calorimeter is made of aluminum.
