A small “coffee cup” calorimeter contains 110. g of H2O at 22.0°C. A 100. g sample of
lead is heated to 90.0°C and then placed in the water. The contents of the calorimeter come to a
temperature of 23.9°C What is the specific heat of lead?

[mass Pb x specific heat lead x (Tfinal-Tinitial)] + [mass water x specific heat water x (Tfinal-Tinitial)] = 0.

I don't get which one is Tfinal, and Tinitial for both of them
can you explain it? thank you
