Answer 2

Given,

23.0 moles of oxygen.

To find,

The number of molecules in the given amount of oxygen.

Solution,

We can simply solve this numerical problem by using the following process:

As per stoichiometry;

1 mole of any element contains Avogadro's number of atoms, that is, 6.022 x 10^23 atoms.

Now,

Number of molecules in 23 moles of oxygen

= 23 × Avogadro's number

= 23 × 6.022 x 10^23 molecules

= 138.5 x 10^23 molecules

= 1.385 x 10^25 molecules

Hence, 23.0 moles of oxygen contains 1.385 x 10^25 molecules.
