# How to find Specific Latent Heat of Fusion of Ice from this question? watch

1. I'm given a scenario where 54g of ice at 0C is placed into a container with 200g of 70C water, both of which (including the container) reaches 40C. Then, 90g of ice at 0C is placed into that container, both of which (including the container) reaches 10C. I am told to ignore heat loss to the surroundings.

Basically what I have done is to find both 'Heat loss by flask + water = Heat gained by ice' for both scenarios and then adding them up before find the Lf. I can't seem to find the answer. However, the solution says that I should take both scenarios and subtract instead of adding and indeed I have gotten the answer. I cannot wrap my head around the concept of latent heat. Any help please? I really feel trapped at this point...
