Which of the following is the correct formula to calculate density?

• A. density = mass / volume
• B. density = volume / mass
• C. density = mass × volume
• D. density = mass + volume

Answer: (A)

Verified step by step guidance

1. Understand that density is a physical property that relates the amount of matter (mass) in a given space (volume).
2. Recall the definition of density, which is the ratio of mass to volume, meaning how much mass is contained in a unit volume.
3. Express this relationship mathematically as \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
4. Recognize that the other options (density = volume / mass, density = mass × volume, density = mass + volume) do not correctly represent this relationship.
5. Conclude that the correct formula for density is \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
