Always put 1 mole = 6.022* 10^23.
1 mole of oxygen atom contains 6.022*10^23 atom wch weighs 16 g .
1 molecule of O2 contains 6.022*10^23 molecules wch weighs 32 g.
U may understand it further by an example ..see ..suppose the question is to calculate the mass of an atom of silver,
Ans . 1 mole =6.022*10^23 =108g .
Mass of 1 atom = 108/6.022*10^23
=108*10^-23/6.022
Now after solving this ..we will get 17.93 * 10^-23.
if the question is to calculate the mass of a molecule of CO2 , in this also u may follow the same steps as given above.
HOPE IT HELPED :)
