The previous answer is correct, but if you assume that your ice is initially at 0 degrees C, then if you divide 1000 cal/79.8 cal/gram, then you'll find the mass of ice that you can melt with 1000 cal.

It depends on how cold the ice is. Many people think of ice as being at 0degC but it can be much much colder. If it is -100deg C you won't melt anything.
