Gold is used for instance
to bridge a gap between two teeth.
If such a bridge were made
of pure gold, it must have a density of
19.0 g per ml.
* Right: The gold
of the bridge weighed 8.6 g.
* Left: In
a measuring cylinder made of a 10 ml syringe the gold of the bridge replaced
0.5 ml of water.
*
The density of the gold sample is 8.6 g/0.5 ml = 17.2 g/ml
