A volume of 75.0 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 21.00 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) Express your answer to three significant figures and include the appropriate units. > View Available Hint(s)

The heat capacity of an object indicates how much
energy that object can absorb for a given increase
in that object's temperature. In a system in which
two objects of different temperatures come into
contact with one another, the warmer object will
cool and the cooler object will warm up until the
system is at a single equilibrium temperature.
A volume of 75.0 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 21.00 C, what is the mass of the steel bar?
Use the following values:
specific heat of water = 4.18 J/(g - "C)
Note the difference between the terms molar heat
capacity, which has units ofJ/(mol - C), and
specific heat, which has units of J/(g. C)
specific heat of steel = 0.452 J/(g "C)
Express your answer to three significant figures and include the appropriate units.
