Question

calculate the gram atomic mass of one atom of oxygen

Answer 1

One mole of oxygen molecule
       Molar mass of oxygen = 16 g/mol
       i.e., the mass of 1 mole of oxygen molecule (O2) = 16 x 2 = 32 g

Answer 2

hey user !!!!!!

ACCORDING TO IUPAC RECOMMANDATION..

we know that ::-
1 mole of anything = in grams unit.

so,, one atom of oxygen has = 16 u.
so 1 mole of oxygen = its molecular quantity but in grams.. = 16 ×2= 32 grams..

Theirfore ,, The requried gram atoimc mass of oxygen = 32 grams .

hope it helps u.. plz mark it as brainliest...
