You put 289 g of hot water at 76 C into a styrofoam container full of 140 g of ice at 0C. What is the final temperature of the mixture?

The latent heat of vaporization is 540 cal/g and the latent heat of fusion is 80 cal/g for water; the specific heat of ice is 0.5 cal/gC and the specific heat of water is 1 cal/gC.

(Your answer should be in calories and given to the ones place, as in the example: 782, and include a - if the answer is negative)
