VSA : Give the number of oxygen molecules in 1 mol of oxygen

Question

Give the number of oxygen molecules in 1 mol of oxygen. [Ans. 6.022 × 10²³]

Answer

6.022 × 10²³

Explanation

One mole of oxygen contains Avogadro’s number (N_A) of oxygen molecules.

The value of Avogadro’s number is approximately 6.022 × 10²³ molecules per mole. Therefore, the number of oxygen molecules in 1 mole of oxygen is:

1 mole of oxygen = Avogadro’s number of oxygen molecules

= 6.022 × 10²³ oxygen molecules
