Question

How many moles of iron are there in 3.82x 10^22 atoms of iron?

Answer 1

Hey there!

There are 6.022 x 10²³ atoms of iron in one mole of iron.

So, divide 3.82 x 10²² by 6.022 x 10²³.

(3.82 x 10²²) ÷ (6.022 x 10²³) = 0.634

There are 0.634 moles of iron in 3.82 x 10²² atoms of iron.

Hope this helps!
