A volume of 89 mL of H2O is initially at room temperature (22.00 oC). A chilled steel rod at 2.00oC is placed in the water. If the final temperature of the system is 20.39oC, what is the mass of the steel bar?
Use the following values: specific heat of water = 4.18 J/(goC); specific heat of steel = 0.452 J/(goC)
