A 0.200 kg block of ice at 15ºC is placed
into a pan on a stove, heated to a liquid, and
then to vapour with a final temperature of
115ºC. Calculate the total amount of heat
required for this process.

If it started out at 15 C, it wasn't ice. Did you leave out a minus sign?
You are going to have to look up the specific heats of ice, water and steam, the heat of vaporization, and the heat of fusion. If you still need help, try posting again.
