Calculate how much energy will be needed to melt the ice, then determine how much energy will be needed to raise the temp of the water from 0 C to 25 C.
Add the two together to find the total.
You will do steps 2 and 3 from this video.
mass of ice (25g in the video - 4,500,000g in this problem)
Heat of fusion value (video uses value in kJ/mol for ice - problem uses value in J/g
Hope this helps!
