Here's why:

* Molar Mass: The molar mass of an element is the mass of one mole of its atoms. It's numerically equal to the atomic mass of the element expressed in grams per mole (g/mol).

* Sulfur's Atomic Mass: The atomic mass of sulfur is approximately 32.065 atomic mass units (amu).

* Conversion: Since one mole of any element contains 6.022 x 10^23 atoms (Avogadro's number), the mass of one mole of sulfur atoms is 32.065 g/mol.
