Which of the following best describes a value for density?

• A. 0.50 mol/L
• B. 8.96 g/cm^3
• C. 25 mL
• D. 100 kg

Answer: (B)

Verified step by step guidance

1. Understand that density is defined as mass per unit volume. The general formula for density is given by \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
2. Look at each option and identify the units involved. Density units typically involve mass units (like grams or kilograms) divided by volume units (like cubic centimeters or liters).
3. Evaluate the first option, 0.50 mol/L. This is a concentration unit (moles per liter), not mass per volume, so it does not represent density.
4. Evaluate the second option, 8.96 g/cm\(^3\). This has units of grams (mass) per cubic centimeter (volume), which matches the definition of density.
5. Evaluate the remaining options, 25 mL and 100 kg, which are units of volume and mass respectively, but not a ratio of mass to volume, so they do not represent density.
