Answer: Number of atoms of Fe = 5.214x10²²atoms

Step-by-step explanation:

First, we'll calculate the number of moles of Fe using the given number of atoms:

Number of moles = Number of atoms / Avogadro's number-----------(i)

Number of atoms of Fe = 5.22x10²²atoms

Avogadro's number = 6.022x10²³atoms/mol)

now putting values in equation (i)

Number of moles = 5.22x10²²atoms ₓ 6.022x10²³atoms/mol)

Number of moles of Fe = 0.0866 moles

To find the number of atoms of Fe, we can use Avogadro's number again:

Number of moles = Number of atoms / Avogadro's number-----------(i)

Number of moles of Fe = 0.0866 moles

Avogadro's number = (6.022x10²³atoms/mol)

Number of atoms of Fe = 5.214x10²²atoms
