Moles of iron = 7.30

<h3>Further explanation</h3>

Given

mass of iron = 408.67 g

Required

moles of atoms

Solution

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

mol iron-Fe (Ar = 56 g/mol)

mol = mass : MW

mol = 408.67 g : 56

mol = 7.30
