To Find :

How many molecules are in 23 moles of oxygen (O₂).

Solution :

We know, 1 mole of any atom/molecule contains 6.022 × 10²³ numbers of atoms/molecules.

So, number of molecules in 23 moles of O₂ are :

$n= 23* 6.022* 10^(23)\\\\n =138.506* 10^(23)\\\\n = 1.385 * 10^(25)\ molecules$

Hence, this is the required solution.
