Question

Calculate the number of moles of iron in a sample containing 10^22 atoms of iron.Try fast guys......

Answer 1

We know that 1 mole of iron = 6.02 * 10^23.

Given that It contains 10^22 atoms of iron = 10^22/6.02 * 10^23

                                                                       = 1/60.2

                                                                       = 0.0166 moles.


Therefore the number of moles = 0.0166 moles.


Hope this helps!

Answer 2

Answer:

Step-by-step explanation:

We know: 1 mole of Fe = 6.022 * 10^23 atoms of Fe

Or vice versa (imp)

Hence, 10^22 atoms of Fe = 10^22/6.022 * 10^23 moles of Fe

Hence 10^22 atoms of Fe has = 1.6605709 * 10^-2 moles
