An ice cube is placed in an empty 80.0g aluminum cup (CAI = 0.900J /(g °C )). The ice cube (Lf= 333] /g , Ly = 2260J /g ) has an initial temperature of 0.00°C while the cup has an initial temperature of 40.0°C. The ice cube completely melts, and the melted ice and the aluminum cup reach a final equilibrium temperature of 10.0°C. No heat is lost to the outside. Calculate the mass of the ice cube (in grams).
