What are the equivalent volumes of hydrogen, oxygen and nitrogen?

1.	What are the equivalent volumes of hydrogen, oxygen and nitrogen?
Answer» SOLUTION :Equivalent volume is the volume occupied by one equivalent of any GAS at NTP. We know, 1 mole of molecules of any gas at NTP occupies 22-4 litres and 1 mole of atoms of any diatomic gas at NTP occupies 11-2 litres. Now, 1 mole of H contains 1 equivalent of H, 1 mole of O contains 2 EQUIVALENTS of O, 1 mole of N contains 3 equivalents of N. THUS at NTP, 1 equivalent of H occupies 11.2 litres, 1 equivalent of O occupies `(11.2)/( 2) = 5.6` litres, 1 equivalent of N occupies `(11.2)/( 3) = 3.73` litres.
