number of oxygen atom present in 1 mole oxalic acid dihydrate?

Dear Student,
Oxalic acid dihydrate is C2​H2​O4​.2H2​O

One molecule of Oxalic acid dihydrate contains 6 oxygen atoms

1 mol of Oxalic acid dihydrate contains 6×Na  (Avogadro number) atoms of oxygen

i.e. 6×6.022×1023=36.13×1023 atoms

Oxalic acid dihydrate     C2H6O6
1 molecule of  C2H6O6 = 2 C atom + 6 O atom + 6H atoms.

1 mole of C2H6O6 = 6.02 x 10*23 C2H6O6 molecules

So, 1 mole of C2H6O6 contains (6 x 6.02 x 10*23) O atoms = = 3.61 x 10*24 O atoms
