Assuming that O2 molecule is spherical in shape with radius , the percentage of the volume of O2 molecules to the total volume of gas at S.T.P. is :
0.09%
0.9%
0.009%
0.045%
As we learnt in
Kinetic Theory of Gases -
Molecules of gases are very small and their actual volume is negligible in comparision to the empty space between them.
