11. A sample of liquid mercury (mass 75 g and temperature 148.0 C)is poured into 98 g of H2O at 18 C. Calculate the final temperatureof the mixture, assuming no heat is lost. The heat capacities of Hgand H2O are 27.98 and 75.33 J/mol/K, respectively.
12. If a chalice made of pure gold weighing 1.1 kg and initially at22 C is filled with 190.0 mL of water at 67 C, what is the finalequilibrium temperature of the system? The heat capacities of waterand gold are 75.29 and 25.42 J/mol/K, respectively.
