Solution:
(I) 48 grams of O3 = NA molecules = 3NA atoms ;
16 grams of O3 = NA/3 molecules = NA atoms ;
(II) 32 grams of O2 = NA molecules = 2NA atoms ;
16 grams of O2 = NA/2 molecules = NA atoms ;
Statement I : 16 grams of ozone contains more number atoms than 16 grams of dioxygen.
Statement II : 16 grams of ozone contains less number molecules than 16 grams of dioxygen.
(I) 48 grams of O3 = NA molecules = 3NA atoms ;
16 grams of O3 = NA/3 molecules = NA atoms ;
(II) 32 grams of O2 = NA molecules = 2NA atoms ;
