you can use the equation:
c=heat transferred/mass X change in temperature
c=2.01J/gC
mass= 104g
chaneg in temp = 40.4C
2.01= x/ 104g x 40.4C
x=8445.21J then divide that number by 1000 to get kJ the answer is 8.44kJ
you can check my calculations but that should be the correct equation.
How many kilojoules of energy are needed to convert 104 g of ice at -14.6 to water at 25.8°C? (The specific heat of ice at -14.6 is 2.01 J/g°C.)
