Four 1-l flasks are separately filled with the gas hydrogen, helium, oxygen and ozone at the same ro — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Since temperature, pressure, and volume are identical, all flasks contain the same number of molecules, say N. Number of atoms in $H_2$ (diatomic) = 2N; in He (monoatomic) = N; in $O_2$ (diatomic) = 2N; in $O_3$ (triatomic) = 3N. Thus, the ratio of atoms is 2:1:2:3.
