Which of the following is the correct formula for density?

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

Answer: (B)

Verified step by step guidance

1. Understand that density is a physical property that relates the amount of mass an object has to the amount of space it occupies (volume).
2. Recall the definition of density, which is the ratio of mass to volume, meaning density tells us how much mass is packed into a given volume.
3. Express this relationship mathematically as \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
4. Recognize that multiplying mass by volume or adding them does not represent density, and dividing volume by mass would give the inverse of density, not density itself.
5. Therefore, the correct formula for density is \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
