1. Find the molar mass of sulfur:
* The molar mass of sulfur (S) is 32.06 g/mol.
2. Calculate the number of moles of sulfur:
* Divide the mass of sulfur by its molar mass:
* moles of sulfur = 16.3 g / 32.06 g/mol = 0.508 moles
3. Use Avogadro's number to find the number of atoms:
* Avogadro's number tells us there are 6.022 x 10^23 atoms in one mole of any substance.
* Multiply the number of moles of sulfur by Avogadro's number:
* number of atoms = 0.508 moles * 6.022 x 10^23 atoms/mol
* number of atoms ≈ 3.06 x 10^23 atoms
Therefore, there are approximately 3.06 x 10^23 atoms in 16.3 grams of sulfur.
