How the volume occupied by 1 mole atom of diatomic gas at NTP will be 11.2 litres?

6 years ago


Answers : (5)


Dear Chanchal,

  Mole = Volume/22.4 (At S.T.P or N.T.P.)

so according to this formula 1 Mole of gas occupies 22.4 litres at N.T.P.


suuppose diatomic gas is O2

 1 mole of O2 gas occupies  22.4 lit at N.T.P.

since O2 consist of two atoms means 1 mole of O2 contains 2 mole atom of oxygen.

thus we can say since 1 mole of O2 or 2 mole atoms of oxygen occupies = 22.4 litres at N.T.P.

therefore 1 mole atom of oxygen occupies = 22.4/2 = 11.2 litres at N.T.P.

Its like that.

1 mole of diatomic gas at STP or NTP=22.4L

this means 2*(i mole of atom not molecule)=22.4

=> 1 mole atom(not molecule)=22.4/2

=11.2 litre.

why one mole gas is having same volume at stp and ntp, both are not same temperatures. according to charles law, v is proportionl to volume.

actually the volume at NTP and STP are not equal. at STP the volume of 1 mole of gas is 22.4 lt but at NTP the volume is 24.02 lt.  you can derive this from PV=nRT
