3.4. Density of a Solid
The density of a solid can be obtained according to the weight of the sample in air, the weight of the
sample in liquid and the density of the liquid.
A
ρ
=
x (
ρ

- d) + d
A - B
ρ
: Density of sample
A : Weight of sample in air
B : Weight of sample in liquid
ρ

: Density of liquid
d : Density of air (approx. 0.001 g/cm

3.5. Density of a Liquid
To measure the density of a liquid, a float with a known volume is used.
The density of a liquid can be obtained according to the weight of the float in air, the weight of the float
in liquid and the volume of the float.
