How many calories of heat must be added to 455 g of steel to raise its temperature from 20 °C to 192 °C? (Note: csteel = 0.115 cal./g. °C.)

Try using the formula Q=mct, where Q is the amount of thermal energy, m is the mass, and t is the change in temperature.
And then c would be the specific heat capacity of steel, so o.115 c/g C

They have given you the formula.

455g * 172°C * .115cal/g °C = 9000 cal
