1 mole ------------- 6.02 x 10²³ atoms
5.10 moles -------- ( atoms sulfur )

atoms sulfur = 5.10 x ( 6.02 x 10²³ ) / 1

atoms sulfur = 3.07 x 10²⁴ / 1

= 3.07 x 10²⁴ atoms of sulfur

hope this helps!

To determine the number of atoms in 5.10 moles of sulfur, we just have to multiply the given number of moles by the Avogadro's number. That is,
                                (5.10 moles) x (6.022 x 10^23 atoms / mole)
                                           = 3.07 x 10^24 atoms
Thus, there are approximately equal to 3.07 x 10^24 atoms of sulfur gas.
