• D. 205.25 g

Answer: (D)

Verified step by step guidance

1. Identify the given information: the density of the fuel is 0.821 g/mL and the volume of the fuel is 250 mL.
2. Recall the formula that relates mass, density, and volume: \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
3. Rearrange the formula to solve for mass: \(\text{Mass} = \text{Density} \times \text{Volume}\).
4. Substitute the given values into the formula: \(\text{Mass} = 0.821\ \text{g/mL} \times 250\ \text{mL}\).
5. Multiply the density by the volume to find the mass of the fuel.
