A volume of 75mL of H2O is initially at room temperature (22C). A chilled steel rod at 2.00 C is placed in the water. If the final temperature of the system is 21.0 Celsius, what is the mass of the steel bar?
Use the following values:
Specific heat of water = 4.18J/(g*C)
Specific heat of steel = 0.452 J/g*C
Express your answer to three significant figures and include appropriate units.
