Question

how many moles are in 4.14 x 10^35 molecules of copper

Answer 1

To answer this question we have to use Avogadro's number, that is the number of molecules present in one mole of any substance.

According to it, there are 6.022x10^23 molecules of copper in one mole of it:

$4.14\times10^{35}moleculesCu\cdot\frac{1molCu}{6.022\times10^{23}moleculesCu}=6.87\times10^{11}molCu$

It means that there are 6.87x10^11 moles of copper.
