Question

A chemist burns a serving of peanuts in a calorimeter and sees that 150000 j of energy is released what should the nutritional label say

Answer 1

35.8 calories

Step-by-step explanation:

Answer 2

We know that

1 calorie = 4.184 Joules

so let us convert the joules to calories first

1 Joule = 1 / 4.184 Cal

150000 = 150000 / 4.184 Cal = 35850.86 Cal

Now in case of food articles

one calorie = 1 Kcal

Therefore on food label it will = 35.851 Cal
