PLEASE HELP ME :

If you combine 400.0 mL of water at 25.00*C and 130.0 mL of water at 95.00*C, what is the final temperature of the mixture? Use 1.00g/mL as the density for water.

Solution

Because you\'re just mixing water, the specific heat is the same for both liquids. So, it\'s just like adding a bunch of weighted numbers:

(400*25 + 130*95)/(400+130) = 22.35°C
