1. Avogadro's Number:
* Avogadro's number tells us the number of atoms or molecules in one mole of a substance. It's approximately 6.022 x 10^23.
2. Molar Mass of Sulfur:
* The molar mass of sulfur (S) is 32.06 g/mol. This means one mole of sulfur atoms weighs 32.06 grams.
3. Calculation:
* Step 1: Calculate the number of moles of sulfur:
(3.09 x 10^24 atoms) / (6.022 x 10^23 atoms/mol) = 5.13 moles of sulfur
* Step 2: Multiply the number of moles by the molar mass to find the mass in grams:
(5.13 moles) x (32.06 g/mol) = 164.4 grams
Therefore, the mass of 3.09 x 10^24 sulfur atoms is approximately 164.4 grams.
