The specific heat capacity of liquid mercury is 0.14 J/g-K. How many kilojoules of heat are needed to raise the temperature of 9.00 g of mercury from 25.1 °C to 65.3 °C?

A calorimeter contained 65.0 g of water at 15.49°C. A 122-g sample of iron at 64.78°C was placed in it, giving a final temperature of 19.22°C for the system. Calculate the heat capacity of the calorimeter. Specific heats are 4.184 J/g.°C for H2O and 0.444 J/g.°C for Fe. Heat capacity of the calorimeter = J/°C
