Respuesta :
A mole is the quantity of a substance that is equal to Avogadro's constant. The 1.993 moles contain [tex]1.2 \times 10^2^4[/tex] atoms of sulfur.
Mole :
It is the amount of substance that contains as many elementary entities as in 12 g of Carbon-12. It is equal to the [tex]\bold{ 6.02 \times 10^2^3}[/tex] atoms, molecules, or ions.
As mentioned above,
1 mole = [tex]\bold{ 6.02 \times 10^2^3}[/tex]
Number of mole formula,
[tex]\bold{ n = \frac{Given Mass }{Molar Mass} }[/tex]
[tex]\bold{ n = \frac{ 1.20 x 10^2^4 }{6.02 \times 10^2^3} }[/tex]
[tex]\bold{n = 1.993}[/tex]
Hence it can conclude that the 1.993 moles contain [tex]1.2 \times 10^2^4[/tex] atoms of sulfur.
