Which of the following best describes how to determine the density of a substance or object?

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

Answer: (B)

Verified step by step guidance

1. Recall the definition of density, which is a measure of how much mass is contained in a given volume of a substance or object.
2. Express the density mathematically as \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
3. Understand that to find the density, you need to measure the mass of the object (usually in grams or kilograms) and the volume of the object (usually in cubic centimeters or liters).
4. Calculate the density by dividing the measured mass by the measured volume using the formula \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
5. Recognize that operations like subtracting, multiplying, or adding mass and volume do not give the correct density value, as density is specifically the ratio of mass to volume.
