Density Practice

Density of water is 1g/ml

Density

Density is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density

DENSITY TRIANGLE

D = M  $\div$  V 
V = M  $\div$  V
M = D  $\times$  V
