A sample of aluminum (specific heat capacity = 0.89 J/goC) is heated to 115.0oC and then placed in 500 mL of water that is at 22.3oC. The final temperature of both the water and the aluminum is
28.3oC. What is the mass of the aluminum that is added to the container, assuming that all the
heat lost by the aluminum is gained by the water? Assume that the density of water is 1.0 g/mL
