A volume of 75 mL of H20 is initially at room temperature (22.00 °C). A chilled steel rod at 2.00°C is placed in the water. If the final temperature of the system is 20.2°C , what is the mass of the steel bar? Use the following values: specific heat of water = 4.18 J/(g°C); specific heat of steel = 0.452 J/(g°C)

Question
A volume of 75 mL of H20 is initially at room temperature (22.00 °C). A chilled steel rod at 2.00°C is
placed in the water. If the final temperature of the system is 20.2°C , what is the mass of the steel
bar?
Use the following values: specific heat of water = 4.18 J/(g°C); specific heat of steel = 0.452 J/(g°C)
Enter your answer numerically, to three significant figures and in terms of grams.
