Question

How many atoms are in 3.75 moles of Fe?

Answer 1

Plug this into your calculator: 3.75 mols FE times 6.02x10^23 atoms FE and you get your answer of how many atoms are in 3.75 mols of FE.

Answer 2

That weird number 6.02x10^23 are how many particles are in 1 mol and it's called Avogadro's number. So there are 6.02x10^23 atoms of FE in 1 mol of FE. That's why you do 3.75 times 6.02x10^23.
