Identify the element in question, which is sulfur (S), and understand that the problem asks for the mass of 1 mole of sulfur atoms.
Recall that the molar mass of an element is the mass of one mole of its atoms, usually expressed in grams per mole (g/mol).
Look up the atomic mass of sulfur on the periodic table, which is approximately 32.06 atomic mass units (amu).
Since 1 mole of atoms corresponds to the atomic mass in grams, the molar mass of sulfur is 32.06 g/mol.
Therefore, the mass of 1 mole of sulfur atoms is equal to the molar mass, which is 32.06 grams.
