The given data is:-
Energy = 2391 Calories
The conversion of calories to J is shown below as:-
1 calorie = 4.184 J
So,
Energy = 4.184 * 2391 J = 10003.944 J
Answer in four significant digits: - 
(b)
The conversion of calories to kJ is shown below as:-
1 calorie = 0.004184 kJ
So,
Energy = 0.004184 * 2391 kJ = 10.003944 kJ
Answer in four significant digits: -
