Approximately 2 moles of sulfur equals 1.2 ×[tex]10^{24}[/tex] atoms of sulfur

We know that 1 mole an element is equal to [tex]6.022*10^{23}[/tex] atoms of it. So 1 mole of sulfur which is 32 g contains [tex]6.022*10^{23}[/tex] atoms.

To calculate the number of moles for 1.2 ×[tex]10^{24}[/tex] atoms, we have to divide this number by 1 mole equivalent of atoms

       ⇒ n = [tex]\frac{1.2*10^{24} }{6.022*10^{23} }[/tex]

       ⇒ n = 2 approximately
