To determine the mass in grams of 0.0458 mole of sulfur (S), we can use the molar mass of sulfur (32.065 g/mol). The molar mass represents the mass of one mole of a substance and provides a conversion factor between moles and grams.

Mass (in grams) = Moles × Molar mass

Mass (in grams) = 0.0458 mol × 32.065 g/mol

Mass (in grams) = 1.469 g

Therefore, the mass of 0.0458 mole of sulfur is approximately 1.469 grams.
