Question

Quizplus · Accepted Answer

The number of sulfur atoms in 1 g of sulfur can be calculated using Avogadro's number and the atomic mass of sulfur. Since the atomic mass of sulfur is 32 u, 1 mole of sulfur weighs 32 grams. Therefore, 1 g of sulfur is 1/32 of a mole. Using Avogadro's number (6 × 10^23 formula units/mole), the number of sulfur atoms in 1 g of sulfur is (6 × 10^23) / 32 = 1.875 × 10^22, which is approximately 1.9 × 10^22.
