Answer:
32.00 g
Explanation:
The molar mass of one atom of oxygen is 16 g/mol.
So for the molecular oxygen or diatomic oxygen O₂:
2 × 16 g/mol
32 g/mol.
16 g of oxygen = one mole of oxygen = 6.022 × 10²³ atoms of oxygen
For O₂.
32 g of oxygen = one mole of oxygen = 6.022 × 10²³ molecules of oxygen
The number 6.022 × 10²³ is called Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
Answer:
32.00 g/mole
Explanation:
The amu of oxygen is 15.99. That times 2 gives about 32.00.
