A volume of 120. mL of H2O 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 21.30 °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)?
The specific heat of water is 4.18 J/(g⋅oC). Calculate the molar heat capacity of water?
Express your answer to three significant figures and include the appropriate units.
