15 mL of 60oC water is mixed with 10 mL of 0oC water in a perfect calorimeter. What is the final temperature?

Answer 1

heat lost by hot water + heat gained by cold water = 0
[mass hot water x specific x (Tfinal-Tinitial)] +[mass cold water x specific heat x (Tfinal-Tinitial)] = 0
Solve for Tfinal.

Answer 2
