Question

the energy produced by the snack in an experiment is calculated to be 14,928 j/g. what is the energy of the snack in calories/gram? snack energy = ? cal/g or kcal/g 1000 cal = 1 kcal remember there are 4.18 j per 1 calorie.

Explanation:

Step1: Convert Joules to calories

We know that \( 1 \text{ cal} = 4.18 \text{ J} \), so to convert \( 14928 \text{ J/g} \) to cal/g, we divide by \( 4.18 \).
\( \frac{14928}{4.18} \text{ cal/g} \approx 3571.3 \text{ cal/g} \)

Step2: Convert calories to kilocalories (Calories)

Since \( 1000 \text{ cal} = 1 \text{ kcal} = 1 \text{ Cal} \), we divide the calorie value by \( 1000 \).
\( \frac{3571.3}{1000} \text{ Cal/g} \approx 3.57 \text{ Cal/g} \)

Answer:

\( 3.57 \) (or approximately, depending on rounding during calculation)
