The smell of rotten eggs comes from dihydrogen monosulfide, which is created through anaerobic respiration of bacteria in low-oxygen environments. In the lab, however, it can be synthesized by reacting aluminum sulfide with water, with aluminum hydroxide as a byproduct. A chemist synthesizes dihydrogen monosulfide and collects 37.8 mL over water at 298 K and 762 mmHg. Assuming water was the excess reactant, what mass of aluminum sulfide was reacted?
