one cup of popcorn that produces 123 kJ when burned in a calorimeter Calculate the kilocalories
To convert from kilojoules (kJ) to kilocalories (kcal), you can use the conversion factor: 1 kcal = 4.184 kJ.
Therefore, the calculation is:
123 kJ * (1 kcal / 4.184 kJ) = 29.4 kcal
So, one cup of popcorn produces approximately 29.4 kilocalories when burned in a calorimeter.
To calculate the kilocalories produced when burning one cup of popcorn, we need to convert the energy from kilojoules to kilocalories.
1 kilocalorie = 4.184 kilojoules
First, let's convert the energy in kilojoules to kilocalories:
123 kJ * (1 kilocalorie / 4.184 kJ) = 29.41 kilocalories
Therefore, one cup of popcorn produces approximately 29.41 kilocalories when burned in a calorimeter.
