Asked by David
A 3.04 g piece of aluminum at 60.0 °C is placed into a “styrofoam cup” calorimeter filled with
150.0 mL of water at 25.0 °C. What is the final temperature of the contents of the calorimeter
once thermal equilibrium has been established (everything has the same final temperature)?
You may need to look up a heat capacity

Tfinal= m1c1T1 + m2c2T2/(m1c1+m2c2)
I found this equation to solve for Tfinal, but not sure how it was derived or if its the correct method to solve this problem

heat lost by Al + heat gained by H2O = 0
[mass Al x specific heat Al x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
The equation you found may be right. I didn't go through the algebra.
