To find the mass of the given number of atoms of sulfur, we need to multiply the number of atoms by the molar mass of sulfur. The molar mass of sulfur is 32.06 g/mol.

Mass of 3.09 × 10^24 atoms of sulfur = 3.09 × 10^24 atoms × 32.06 g/mol = 9.91 × 10^25 g = 165 g (rounded to three significant figures).

Therefore, the correct answer is C, 165.
