Excess ice at 0 c is placed in an insulated cup containing 515 g of soft drink at 23 c. The specific heat of the drink is the same as that of water (4.184 J/g c). Some ice remains after the drink cools to 0 c. Determine the mass of ice that has melted. Assume that the heat capacity of the cup can be ignored. It takes 334 J to melt 1.00 g of ice at 0 c.
