Final answer:
The mass of 1 mole of sulfur atoms is 32 grams, which corresponds to the molar mass of sulfur.
Step-by-step explanation:
The question is asking us to determine the mass of 1 mole of sulfur atoms. By definition, the molar mass of an element is the mass of one mole of that element's atoms. The molar mass of sulfur is 32 g/mol; therefore, 1 mole of sulfur atoms has a mass of 32 grams (option a.) This is a fundamental concept in chemistry, especially when dealing with stoichiometry and chemical equations.
