Approximately how many ice cubes must melt to cool 1150 milliliters of water from 29°C to 0°C? Assume that each ice cube contains 1 mole of H2O and is initially at 0°C.
∆H(fusion) = 6.02 kJ/mol; ∆H(vaporization) = 40.7 kJ/mol
c(solid) = 2.09 J/g°C; c(liquid) = 4.18 J/g°C; c(gas) = 1.97 J/g°C
Enter your answer numerically.
