Understanding Density: Why Milliliters Can't Measure Density
Explore why density is expressed in g/cm³, not milliliters, and learn how to calculate it accurately.

Density cannot be measured in milliliters. Density is typically expressed in units like grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). Milliliters (mL) are a unit of volume, not density. For example, if you have 100 grams of a substance occupying 50 milliliters, the density would be calculated as 100 g / 50 mL = 2 g/mL.
FAQs & Answers
- What is density? Density is the mass of a substance divided by its volume, often expressed in g/cm³ or kg/m³.
- Can I use milliliters to describe density? No, milliliters are a unit of volume. Density is expressed in relation to mass and volume, like g/cm³.
- How is density calculated? Density is calculated by dividing the mass of an object by its volume (Density = Mass/Volume).
- Why is it important to differentiate between volume and density? Understanding the difference is crucial for correct scientific measurements and applications in chemistry and physics.
