Question: The heat of vaporization of water is 2260 J/g at 100°C. A 100.0 g sample of water condenses and all of the heat liberated is then transferred to a block of ice. How many grams of ice will melt? Assume the condensed water remains at 100°C and the melted ice remains at 0°C. The heat of fusion of ice is 335 J/g. I am totally confused by this question, and I don't even know how to start. Can someone explain this question to me, or just give some hints?
