During the late 1800's, hard rock miners replaced candles with carbide lamps for work in mine shafts. The lamps worked by dripping water onto calcium carbide that generated acetylene gas (H2C2) that was burned. If the reaction is CaC2 + 2H2O -> H2C2 + Ca(OH)2, how many liters of acetylene gas at 1.00 atm pressure and 0.00 o C are produced from 75.0 grams of calcium carbide (CaC2)?
