Question

* Calculate the mass of one atom of oxygen?​

Answer 1

$\huge{\underline{\underline{Solution}}}$

$\sf{O_2\: is\: a\: diatomic\: molecule}$

⟹ The mass of an oxygen atom = 16 amu.

∴ Mass of $\sf{O_2}$ molecule = 2 × 16 = 32 amu.

Mass of one molecule of oxygen

⇝ ${\dfrac{32}{Avogadro\: constant ( 6.023 × 10^2³)}}$

⇝ $5.3 × 10^-²³$

Answer 2

Answer:

$\huge{\underline{\underline{Solution}}}$

Solution

$\sf {O_2\: is\: a\: diatomic\: molecule}O²$

⟹ The mass of an oxygen atom = 16 amu.

∴ Mass of {O_2}O²

molecule = 2 × 16 = 32 amu.
