1. The problem statement, all variables and given/known data How much ice must melt at 0 deg. C to gain 5 g of mass? Latent Heat of Fusion = 2. Relevant equations I cannot seem to find many equations that relate thermodynamics and mass, maybe that is my biggest problem... The only one i could find was Q=Lm 3. The attempt at a solution I know the latent heat of fusion, but i do not know Q. I tried dividing both sides by L, giving me Q/L=m, but i wasn't sure where to go from there.
