If 35.0 g H2O at 22.7 °C is combined with 65.0 g H2O at 87.5 °C, what is the final temperature of the mixture? The specific heat capacity of water is 4.184 J/g×K.

Question

If 35.0 g H2O at 22.7 °C is combined with 65.0 g H2O at 87.5 °C, what is the final temperature of the mixture? The specific heat capacity of water is 4.184 J/g×K.

DrBob222 · Accepted Answer

heat gained by cold water + heat lost by hot water = 0

heat gained by cold water is
[mass H2O x specific heat H2O x (Tfinal-Tintial)]

heat lot by hot water is
[mass H2O x specific heat H2O x (Tfinal-Tinitial)]

Substitute and solve for Tfinal.
