1. Find the molar mass of sulfur:
* The molar mass of sulfur (S) is 32.06 g/mol. This means 1 mole of sulfur atoms weighs 32.06 grams.
2. Calculate the number of moles in 100g of sulfur:
* Divide the mass of sulfur by its molar mass:
* Moles of sulfur = 100 g / 32.06 g/mol = 3.12 mol
3. Use Avogadro's number to find the number of atoms:
* Avogadro's number states that there are 6.022 x 10^23 atoms in 1 mole of any substance.
* Multiply the number of moles by Avogadro's number:
* Atoms of sulfur = 3.12 mol * 6.022 x 10^23 atoms/mol ≈ 1.88 x 10^24 atoms
Therefore, there are approximately 1.88 x 10^24 atoms in 100g of sulfur.
