when measuring latent heat, why should your final temperture be the minimum temperature reached by the calorimeter?

"final temp" I am assuming is the point where the ice has melted, which was a result of the latent heat of the frozen ice.
A 10 g of steam initially at 100 ⁰C is mixed with 50 g of ice at
-10 ⁰C. What will be the final temperature of the mixture?
