90.0 mL of rm H_2O is initially at room temperature (22.0rm{} ^{circ}C). A chilled steel rod at 2.0rm ^{circ}C is placed in the water. If the final temperature of the system is 21.4^{circ}C, what is the mass of the steel bar?Specific heat of water = 4.18 rm J/g{cdot}^{circ}CSpecific heat of steel = 0.452 rm J/g{cdot}^{circ}C
