Which of the following correctly describes how to calculate the density of an object?

• A. Divide the mass of the object by its volume.
• B. Subtract the volume from the mass of the object.
• C. Multiply the mass of the object by its volume.
• D. Add the mass and volume of the object together.

Answer: (A)

Verified step by step guidance

1. Recall the definition of density in chemistry, which is a measure of how much mass is contained in a given volume.
2. Understand that density is calculated by dividing the mass of an object by its volume, which can be expressed as the formula: \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
3. Recognize that subtracting, multiplying, or adding mass and volume does not provide a meaningful physical property related to density.
4. Identify that the correct method to find density is to take the mass (usually in grams) and divide it by the volume (usually in cubic centimeters or milliliters).
5. Conclude that the correct description is: 'Divide the mass of the object by its volume.'
