Question

29 Define atomicity. How is Avogadro's law useful
in deciding atomicity of a gas?​

Answer 1

Answer:

Avogadro hypothesis states that equal volume of all gases under similar conditions of temperature and pressure contain equal number of molecules. One of the applications of Avogadro's law is to calculate atomicity of elementary gases. ... For example oxygen molecule has two oxygen atoms. So, atomicity of O2 is 2.
