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.

How much ice (in grams) would have to melt to lower the temperature of 351 mL of water from 26 ∘C to 6 ∘C? (You must consider the enthalpy in cooling the water, as well as the enthalpy in melting the ice and the enthalpy to heat the melted ice from 0∘C up to the system's final temperature of 6 ∘C. Also assume that the density of water is 1.0 g/mL.)
