>How many joules of heat are needed to change 50.0 grams of ice at -15.0 degrees celsius to steam at 120.0 degrees celsius?

I fucking missed this and now I'm lost. I'm supposed to use these equations multiple times or something:
[math]q=mC\DeltaT[/math]
[math]q=n\Delta H_{fusion or vapor}[/math]

What's the difference between these equations and what do I actually do with them?
