If 16 g of oxygen contains 1 mole of oxygen atoms, calculate the mass of one atom of oxygen.

Academic Chemistry NCERT Class 9

Mass of 1 mole of oxygen = 16g

1 mole of oxygen contains 6.022 × 10²³ oxygen atoms.

Mass of 6.022 × 10²³ oxygen atoms = 16g

Mass of 1 oxygen atom = 16/ (6.022 × 10²³)

Therefore, 1 atom of oxygen molecule weighs 2.65 × 10^-23grams.
