Answer:
1.506 × 10^24 atoms
Step-by-step explanation:
To determine the number of atoms of sulfur (S) you have if you have 2.5 moles of S, you can use Avogadro's number, which relates the number of particles (atoms, molecules, etc.) to the amount in moles.
Avogadro's number is approximately 6.022 × 10^23 particles per mole. Therefore, to find the number of atoms in 2.5 moles of S, you can multiply the number of moles by Avogadro's number:
Number of atoms of S = 2.5 moles x 6.022 × 10^23 atoms/mole
Number of atoms of S = 1.506 × 10^24 atoms
So, if you have 2.5 moles of S, you would have approximately 1.506 × 10^24 atoms of S.
