We have an unknown mass (msteel) of steel at a temperature (Tsteel = 90 °C ), that it is placed in a 30.0g aluminum calorimeter containing 70.0g of water. The water and calorimeter are both initially at a temperature ( T; = 20 °C ). After you mix the hot and cold systems, the final equilibrium temperature is (T† = 50 °C), determine the mass (msteel) of %3D the steel.
