A sample of gold is at a initial temperature of 350 k. Once dropped into a coffe cup calorimeter of heat capacity 400 k^-1 it contains 50 g of water at 300 k. Specific heat capacity is 0.129 for gold and 4.18 for water. what is the final temp of all gold, coffee cup, and water.

heat lost by Au + heat gained by water = 0
[mass Au x specific heat Au x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for Tfinal.
[mass Au x specific heat Au x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for Tfinal.
