Calculations Involving DensityIntroduction to the Density Formula

Page 2: Calculations Involving Density Introduction to the Density Formula

Density is defined as Mass per Unit Volume.

Page 3: Calculations Involving Density Introduction to the Density Formula

Density is defined as Mass per Unit Volume.Mass and volume are both extrinsic properties. Their values depends on the quantity of the substance you have.

Page 4: Calculations Involving Density Introduction to the Density Formula

Density is defined as Mass per Unit Volume.Mass and volume are both extrinsic properties. Their values depends on the quantity of the substance you have.

For example, 1 penny has a mass of 2.35 g and a volume of 0.413 cm3.

Page 5: Calculations Involving Density Introduction to the Density Formula

Density is defined as Mass per Unit Volume.Mass and volume are both extrinsic properties. Their values depends on the quantity of the substance you have.

For example, 1 penny has a mass of 2.35 g and a volume of 0.413 cm3.While 2 pennies have a total mass of 4.70 g and a total volume of 0.816 cm3.
