The number of moles : 6.2 x 10¹¹
Further explanation
The mole is the number of particles contained in a substance
1 mole = 6.02.10²³ particles
[tex]\tt N=n\times No[/tex]
N = number of particles
n = moles
No = Avagadro's number : 6.02.10²³
3.73 x 10³⁵ atoms of S
the number of moles :
[tex]\tt \dfrac{N}{No}=\dfrac{3.73\times 10^{35}}{6.02\times 10^{23}}=6.2\times 10^{11}[/tex]
