molar wt of O2 molecule = 32g
and given wt is 40g
so no.of moles of Oxygen is =40/32=1.25..moles ........as no.of molecules of CO2 and Oxygen are same so moles should same for both.....So moles CO2 also should be 1.25
and molar wt of CO2 is 44g ..so given wt of CO2= no.of moles* molar wt = 1.25 * 44=
55g ...
and given wt is 40g

I was taking atomic mass of oxygen is 16g
O IS ATOM here molecule is described...so u should take O2
i got that
