Question

One mole of oxygen molecule have

• A. Avogadro Number
• B. 1 GMM
• C. 1 GAM
• D. All of the above.

Answer 1

The correct option is D

All of the above.

1 mole of any compound contains $6.02\times {10}^{23}$ molecules.
Every oxygen molecules contains 2 oxygen atom.
$\therefore$ Number of atoms present in 1 mole of oxygen molecule = $2\times 6.02\times {10}^{23}=12.04\times {10}^{23}$ atoms.
Gram molecular mass of oxygen is 32 g.
