Question

Perform the conversions between energy units.

328 kJ = ______ kcal.
3375 kcal = ______ kJ.
9.90 x 10^6 J = ______ kcal.

Answer 1

To convert energy units, 328 kJ is equal to 78.38 kcal, 3375 kcal is equal to 14,117.25 kJ, and 9.90 x 10^6 J is equal to 2,360.98 kcal.

Step-by-step explanation:

To convert between energy units, we can use the conversion factor 1 kcal = 4186 J.

1. 328 kJ = 328,000 J = (328,000 J) / (4186 J/kcal) = 78.38 kcal
2. 3375 kcal = 3375 kcal * (4186 J/kcal) = 14,117,250 J = 14,117,250 J / 1000 = 14,117.25 kJ
3. 9.90 x 10^6 J = 9.90 x 10^6 J / (4186 J/kcal) = 2,360.98 kcal
