3.3 moles of sulfur
Explanation:
To find the number of moles knowing the number of atoms we use Avogadro's number to formulate the following reasoning:
if in 1 mole of sulfur (S) there are 6.022 × 10²³ atoms of sulfur (S)
then in X moles of sulfur (S) there are 2 × 10²⁴ atoms of sulfur (S)
X = (1 × 2 × 10²⁴) / (6.022 × 10²³)
X = 3.3 moles of sulfur
