Verified step by step guidance

Identify the concept of density: Density is a measure of how much mass is contained in a given volume.

Recall the formula for density: Density is calculated as the mass of a substance divided by its volume.

Express the formula mathematically: \( \text{Density} = \frac{\text{Mass}}{\text{Volume}} \).

Understand the units: Typically, mass is measured in grams (g) and volume in cubic centimeters (cm³) or milliliters (mL), so density is often expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Apply the formula: To find the density of a substance, divide the mass by the volume using the formula \( \text{Density} = \frac{\text{Mass}}{\text{Volume}} \).
