1. Find the molar mass of sulfur:
* The molar mass of sulfur (S) is 32.06 g/mol. This means one mole of sulfur weighs 32.06 grams.
2. Calculate the number of moles of sulfur:
* Divide the mass of sulfur by its molar mass:
* Moles of sulfur = (3 grams) / (32.06 g/mol) = 0.0936 moles
3. Use Avogadro's number to find the number of atoms:
* Avogadro's number tells us that there are 6.022 x 10^23 atoms in one mole of any element.
* Multiply the number of moles of sulfur by Avogadro's number:
* Number of sulfur atoms = (0.0936 moles) * (6.022 x 10^23 atoms/mol)
* Number of sulfur atoms ≈ 5.64 x 10^22 atoms
Therefore, there are approximately 5.64 x 10^22 sulfur atoms in 3 grams of sulfur.
