if you have 380.0mL of water at 25.00 degrees Celsius and add 140mL of water at 95.00 degrees Celsius, what is the final temperature of the mixture? Use 1.00 g/mol as the density of water.

heat gained by cool water + heat lost by warm water = 0
[mass cool H2O x specific heat x (TfinalTintial)] + [mass warm water x specific heat x (TfinalTinitial)] = 0
Solve for Tf.
