Description

Density (σ) is defined as mass (m) per unit volume (V):

In experiment C3.1.1.1, a sphere of known volume with two stopcocks is used to determine the density of various gases. The mass of the enclosed air is determined from the measured difference between the total weight of the sphere filled with gas and the empty weight of the evacuated sphere.
