Density definition: Amount of mass (in grams - g) per a unit of volume (in liters - L - or milliliters - ml). Formula: Density = mass/volume Density unit: g/ml

Density How do you determine mass? How do you determine volume of something odd shaped?

Density is a "fingerprint property, " meaning it can be used to identify substances. Each substance has a characteristic density.

Density Suppose a king wanted you to make sure his crown were pure gold. How would you do it?
