1. Convert Atoms to Moles:
* Avogadro's number tells us there are 6.022 x 10^23 atoms in one mole of any substance.
* Divide the number of sulfur atoms by Avogadro's number:
(3.91 x 10^24 atoms) / (6.022 x 10^23 atoms/mol) = 6.49 moles of sulfur
2. Calculate Mass from Moles:
* The molar mass of sulfur (S) is 32.06 g/mol.
* Multiply the number of moles by the molar mass:
(6.49 moles) * (32.06 g/mol) = 208 g
Therefore, the mass of 3.91 x 10^24 sulfur atoms is approximately 208 grams.
