50ml of water at 49.6 C were mixed with 50ml of water at 25.1 C in a calorimeter also at 25.1 C. The final temperature was 30.1 C Assuming that neither the density of water nor its specific heat capacity change with temperature, calculate the total heat capacity of the calorimeter.

Answer 1

[mass warm H2O x specific heat x (Tfinal-Tinitial)] + [mass cool H2O x specific heat x (Tfinal-Tinitial)] + [Ccal x (Tfinal-Tinitial) = 0\
Substitute and solve for Ccal.
