Answer :
Avagadros number states that 1 mol of any substance consists of 6.022 x 10^23 units.
These units could be molecules making up a compound or atoms making up an element.
Therefore 1 mol of Fe consists of 6.022 x 10^23 molecules of Fe
The weight of 1 mol is molar mass. Molar mass of Fe is 55.8 g/mol
6.022 x 10^23 molecules of Fe weighs 55.8 g/mol
Therefore 6.02 x 10^23 molecules weigh - 55.8 /(6.022x10^23) x 6.02 x 10^23 molecules
Mass of Fe -55.8 g

Avogadro's number is the factor for proportionality for the constituents of particle number to that of the amount. The mass of iron in a gram is 55.8 gm.
What is mass?
Mass represents the quantity in grams or kilograms of the substance in the given sample.
In 1 mole of any substance, the Avagadro's number is [tex]6.022 \times 10^ {23}\;\rm units.[/tex]Thus, 1 mole of iron will contain, [tex]6.022 \times 10^ {23} \;\rm molecules[/tex] iron. The molar mass of Fe is 55.8 g/mol.
The mass of [tex]6.022 \times 10^ {23}[/tex] molecules is given as,
[tex]\dfrac{55.8}{(6.022 \times 10^ {23})} \times 6.022 \times 10^ {23}\;\rm molecules[/tex]
Therefore, 55.85 grams of iron will be present.
