How many atoms of iron are there in 1 moles of wolframite FeWO4?

As it can be seen from the molecular formula of wolframite that is FeWO₄, that there is one mole of iron that is Fe in 1 mole of wolframite ( FeWO₄).

1 mole of Fe= 1 × 6.023 × 10 ²³ atoms of Fe

So there are 6.023 × 10 ²³ atoms of Fe are there in 1 moles of wolframite, FeWO₄.

So number of atoms of iron is  6.023 × 10 ²³ in 1 moles of wolframite, FeWO₄.
