How much ice (in grams) would have to melt to lower the temperature of 350 ml of water from 25 ∘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.)
