## How do you find the atoms of an element in a compound?

They are:

1. Mass → Moles and Moles → Atoms.
2. 196.967 u . …
3. So if you are given the mass of an element you use the periodic table to find its molar mass and multiply the given mass by the reciprocal of the molar mass. …
4. Once you have moles multiply by Avogadro’s number to calculate the number of atoms.

## How many atoms of iron are there in iron oxide?

two atomsThe formula for iron (iii) oxide is Fe2O3 F e 2 O 3 so there would be two atoms of iron present. In order to form a stable molecule the combined charges of the atoms in the molecule must equal to zero. In this case iron would have a charge of +3 on each of its atoms due to the iron being in the iron (iii) form.
