1.4 THE VARIETY OF RESOURCES ON EARTH THE CONCEPT OF DENSITY

The density of substance is the mass of the substance in a unit volume. The unit for density is kg/m³ or g/cm³ DENSITY (D) =

MASS (M) VOLUME (V)

1. What is ………… M a. D = _______ D V

V

= _________

Example 1

The mass of 5cm³ of iron is 10.0g. What is its density? The density of iron =

= =

Mass Volume 10.0g 5cm³ 2 g/cm³

2.The mass of an object is 30 g. What is its density if it has a volume of 12 cm³ ?
