Question
A 30.0 g sample of water at 280. K is mixed with 50.0 g of water at 330 K. Calculate the final temperature of the mixture assuming no heat loss to the surroundings. Remember that the heat gained by the cooler water is equal to the heat lost by the warmer water.

c = cool
w = warm
[mass w H2O x specific heat H2O x (Tfinal-Tinitial)] + [mass c H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Subsitute and solve for Tfinal.
