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*10^(35)moleculesCu\cdot(1molCu)/(6.022*10^(23)moleculesCu)=6.87*10^(11)molCu`

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