Question

a calorimeter absorbs 36,200 j of energy from the snack shown in the data below. how much energy does the snack provide per gram (j/g) according to the experiment?
snack data
initial mass (g) 3.15
final mass (g) 1.85
$q_{snack} = ? j/g$

Explanation:

Step1: Calculate mass of snack burned

The mass of the snack burned is the initial mass minus the final mass. So, \( 3.15 - 1.85 = 1.3 \) g.

Step2: Calculate energy per gram

Energy per gram (\( q_{\text{snack}} \)) is total energy absorbed divided by mass burned. So, \( \frac{36200}{1.3} \approx 27846.15 \) J/g.

Answer:

\( \approx 27846.15 \)
