Be more specific: How much ice? How much heat? We can help you with your homework if you'll give us what you think the answer should be first.

The equation usually need for this is:

Q = mL

but then, there is also

Q = mcT

which needs to be used if the ice is not at melting point.

So, what is exactly required is the mass and temperature of the ice, and you have to have the values of c and L provided to you.
