Vedclass · Answer

(D) The mass of one atom of an element is calculated by dividing its atomic mass by the Avogadro constant $(N_A)$.The atomic mass of oxygen is $16 \, u$.The Avogadro constant $(N_A)$ is approximately $6.023 	imes 10^{23} \, 	ext{mol}^{-1}$.Therefore,the mass of one atom of oxygen $= \frac{	ext{Atomic mass}}{N_A} = \frac{16}{6.023 	imes 10^{23}} \, g$.
