32g/mol. The molar mass of an oxygen atom is ~15.999995, which is pretty much 16. Since oxygen is diatomic, you would multiply the molar mass of one atom by two (16 x 2) to get 32 g/mol

Answer: 32 g/mol

Explanation:

According to Avogadro's law, 1 mole of every substance contains avogadro's number [tex](6.023\times 10^{23})[/tex] of particles and weighs equal to its molecular mass.

Diatomic molecule is a molecule formed by combination of two atoms of the same element. Example: [tex]O_2[/tex]

1 mole of oxygen [tex]O_2[/tex] molecule contains = 2 moles of oxygen atoms

1 mole of oxygen atom weigh= 16 g

2 moles of oxygen atoms weigh =[tex]\frac{16}{1}\times 2=32 g[/tex]

Thus 1 mole of oxygen molecule weigh 32 g.
