A sample of liquid mercury (mass 58 g and temperature 149.0 C) is poured into 79 g of H2O at 19 C. Calculate the final temperature of the mixture, assuming no heat is lost. The heat capacities of Hg and H2O are 27.98 and 75.33 J/mol/K, respectively.

Answer 1

See the Au and H2O. All of the use the same concept and the same formula.
heat lost by one + heat gained by other = 0
