100. Density 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

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

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