When ice melts, it absorbs 0.33 kJ per gram. How much ice is required to cool a 10.0 oz drink from 77 ∘F to 40 ∘F, if the heat capacity of the drink is 4.18 J/g∘C? (Assume that the heat transfer is 100 % efficient.)

You must know the temperature of the ice before this problem can be worked. It may be 0oC but it could be anything below that.
