1. Convert kilograms to grams:
* 1 kg = 1000 g
* 425.0 kg * 1000 g/kg = 425,000 g
2. Calculate the moles of sulfur:
* Molar mass of sulfur (S) = 32.065 g/mol
* Moles of sulfur = (mass of sulfur) / (molar mass of sulfur)
* Moles of sulfur = 425,000 g / 32.065 g/mol = 13,255.6 mol
3. Calculate the number of sulfur atoms:
* Avogadro's number = 6.022 x 10^23 atoms/mol
* Number of sulfur atoms = (moles of sulfur) * (Avogadro's number)
* Number of sulfur atoms = 13,255.6 mol * 6.022 x 10^23 atoms/mol
* Number of sulfur atoms = 7.98 x 10^27 atoms
Therefore, there are approximately 7.98 x 10^27 sulfur atoms in 425.0 kg of sulfur.
