... you need a constant called the latent heat of fusion. I'm sure this is in your book somewhere .. If I remember it correctly it is 335 J/g
just multiply the mass in grams by this constant ..
Q = m X Lf = 335g X 335J/g = 112,225 J
convert to kJ ... divide by 1000 = 112.225 kJ <<< round for sig. figs
Q = 112kJ >>> answer
