Question

calculate the molar mass of oxygen atoms​

Answer 1

Explanation:

O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu. ⇒ 5.31 × 10-23g.

Answer 2

Answer:

The oxygen atom has an atomic mass of $16.00 gmol^-^1$.

Explanation:

• Oxygen is a element with the atomic number $(8)$ and with symbol $O$. It is a highly reactive nonmetal and an oxidizing agent that rapidly produces oxides with most elements and other compounds. It belongs to the chalcogen group of the modern periodic table.
• As we know that it has an atomic mass of $16.00 amu$  which translates to a molar mass of $16.00 gmol^-^1$. Now, since, the oxygen atom has a mass of $16.00 amu$.
• ∴ Oxygen has molecule mass$= 2X16 = 32 amu$.
