How many moles are in 5.0 x 10^25 atoms of iron?

Andreas93 [3]

Hello!

To find the number of moles that are in the given amount, we need to divide the total number of atoms by Avogadro's number, which is 1 mole is equal to 6.02 x 10^23 atoms.

5.0 x 10^25 / 6.02 x 10^23 ≈ 83.0564

Therefore, there are about 83.06 moles of iron (sigfig: 83 moles).
