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) = M A SS ( 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 = M a ss Volume

= 1 0 . 0 g 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 ?

3.The volume of R was determined to be 40cm³ in an experiment. If the density of solid R is 0.5 g/cm³. What is its mass?

4.The mass of piece of stone is 360g and its volume is 200cm³. What is the density of the stone?

A less dense substance FLOATS in a denser liquid

Whereas a denser substance SINKS in a less denser liquid
