× 1023 mol-1)

One mole of any substance contains Avogadro's number of particles, which is 6.02 × 1023.

A triatomic gas means a molecule of the gas contains three atoms.

0.1 mole of the gas will contain:

0.1 mole x 6.02 × 1023 mol-1 = 6.02 × 1022 molecules

Each molecule contains 3 atoms, therefore:

6.02 × 1022 molecules x 3 atoms/molecule = 1.806 × 1023 atoms

Therefore, there are 1.806 × 1023 atoms in 0.1 mole of a triatomic gas.
