1. Find the molar mass of sulfur:
* The molar mass of sulfur (S) is 32.06 g/mol. This means 1 mole of sulfur weighs 32.06 grams.
2. Calculate the number of moles of sulfur:
* Divide the given mass of sulfur by its molar mass:
* moles of sulfur = (5.10 g) / (32.06 g/mol) = 0.159 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 element.
* Multiply the number of moles of sulfur by Avogadro's number:
* number of atoms = (0.159 mol) * (6.022 x 10^23 atoms/mol)
* number of atoms = 9.58 x 10^22 atoms
Therefore, there are approximately 9.58 x 10^22 atoms in 5.10 grams of sulfur.
