Given:

Formula units of FeCl₃ = 8.65 x 10²³ formula units

Unknown:

Mass of the FeCl₃ = ?

Solution:

The formula unit is the same as the amount of subatomic particles in an atom.

1 mole of a substance = 6.02 x 10²³ formula units

For 8.65 x 10²³ formula units; the number of moles;

Number of moles = $\frac{8.65 x 10 ^{23} }{6.02 x 10^{23} }$ = 1.44moles

Now to find the mass of FeCl₃;

Mass of FeCl₃ = 1.44 x 162.2 = 233.1g
