Question

A chemist burns a serving of chocolate in a calorimeter and finds that 30,000 J of energy is released. What should the nutritional label read in Calories (not calories)? (I cal = 4.184 J)

Answer 1

Here, 1 J = 1/ 4.184 Cal
So, 30,000 J = 30000/4.184 = 7170.17 Cal

In short, Your Answer would be 7170.17 Cal

Hope this helps!
