Question

If a gaseous mixture contains o2 and co2 in the volume ratio of 1:3 at STP then the ratio of the number of atoms in the mixture will be​

Answer 1

Volume Ratio = 1:3

According to Avogadro's Law,

Mole Ratio = 1:3

Ratio of number of molecules = 1 : 3

Ratio of number of atoms = 1 × 2 : 3 × 3

                                           = 2 : 9
