The formation of condensation on a glass of ice water causes the ice to melt faster than it would otherwise. If 7.42 g of condensation forms on a glass containing water and 397 g of ice, how many grams will melt as a result? Assume no other heat transfer occurs. The latent heat of vaporization of water is 539 kcal/kg and the latent heat of fusion for ice is 79.8 kcal/kg.
