Hydrogen sulfide (H2S), a toxic gas redolent of sewage and rotten eggs, is prepared from hydrochloric acid and sodium sulfide by this reaction: 2HCl(aq) + Na2S(aq) → H2S(g) + 2NaCl(aq). Determine the percent yield if 3.75 L of H2S at STP is produced from reacting 37.9 g HCl (36.46 g/mol) and 19.7 g of Na2S (78.04 g/mol). Don't enter the percent symbol in your answer, just the value.
