A piece of a newly synthesized material of

Question

mass 25.0 g at 80.0
◦
C is placed in a calorimeter containing 100.0 g of water at 20.0
◦
C. If
the final temperature of the system is 24.0
◦
C,
what is the specific heat capacity of this material?

Answer 1

[mass material + specific heat material x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for Tfinal.

Answer 2
