A Styrofoam bucket of negligible mass contains 1.55 kg of water and 0.435 kg of ice. More ice, from a refrigerator at -15.0 ∘C, is added to the mixture in the bucket, and when thermal equilibrium has been reached, the total mass of ice in the bucket is 0.772 kg . Assuming no heat exchange with the surroundings, what mass of ice was added?

Initially you have mW = 3.4 kg of water at
TW = 54°C in an insulated container. You add
ice at TI = -21°C to the container and the mix
reaches a final, equilibrium temperature of Tf
= 25°C. The specific heats of ice and water are
cI = 2.10×103J/(kg⋅°C) and
cW = 4.19×103 J/(kg⋅°C),
respectively, and the latent heat of fusion for water is
Lf = 3.34×105 J/kg.
