Which of the following is the correct measure of density?

• A. mass plus volume
• B. mass multiplied by volume
• C. mass divided by volume
• D. volume divided by mass

Answer: (C)

Verified step by step guidance

1. Recall the definition of density in chemistry: Density is a measure of how much mass is contained in a given volume of a substance.
2. Express this relationship mathematically as density \(= \frac{\text{mass}}{\text{volume}}\).
3. Understand that density is not the sum or product of mass and volume, but rather the ratio of mass to volume.
4. Evaluate the options given: 'mass plus volume' and 'mass multiplied by volume' do not represent density because they do not express a ratio.
5. Confirm that 'mass divided by volume' correctly represents density, while 'volume divided by mass' is the inverse and thus incorrect for density.
