Understanding Density

Density is a measure of how much mass is contained in a given volume. It's calculated using the formula:

* Density = Mass / Volume

Calculation

1. Mass: 24.5 grams

2. Volume: 8.7 cm³

Density = 24.5 grams / 8.7 cm³ ≈ 2.82 g/cm³

Answer: The density of the rock is approximately 2.82 grams per cubic centimeter (g/cm³).
