Question

if burning one gram of carbohydrates yields 17,243 joules (j) of energy and requires 829 milliliters of oxygen, this is the same as saying 20.8 joules per ml (j/ml). how much energy from carbohydrates would the stackarel use when consuming 50 milliliters of oxygen? a) 1612 j b) 1042 j c) 531 j d) 735 j

Explanation:

Step1: Identify energy - per - mL ratio

The energy per mL of oxygen when burning carbohydrates is 20.8 J/mL.

Step2: Calculate energy for 50 mL of oxygen

We use the formula $E = r\times V$, where $r$ is the energy - per - mL ratio and $V$ is the volume of oxygen. Substituting $r = 20.8$ J/mL and $V = 50$ mL, we get $E=20.8\times50 = 1040$ J (close to 1042 J due to possible rounding in the given values).

Answer:

B. 1042 J
