Density is the amount of mass of a substance that fits in a given volume. Density is defined as:

Measure the mass of the solid object (rectangular blocks) using a top-pan balance.

Apparatus

Some irregular solids, 0-500 ml measuring cylinder, top-pan balance is required to perform this experiment.

Density of Helium

A helium-filled balloon moves upwards because the density of the helium gas is less than density of air.

Measure the mass of the rectangular wooden block in grams by using a top-pan balance.
