Calculate the number of iron atoms in 125 moles of iron.
The number of iron atoms in 125 moles of iron can be calculated as follows:
1 mole of any substance contains Avogadro's number of atoms. Avogadro's number is defined as 6.022 x 10^23 atoms per mole.
Therefore, 125 moles of iron contains:
6.022 x 10^23 atoms/mole x 125 moles = 753.75 x 10^23 atoms
So, the number of iron atoms in 125 moles of iron is 753.75 x 10^23 atoms
