Calcium carbide reacts with water to produce acetylene gas according to the following equation: CaC₂ (s) + 2H₂O(1)→ C₂ H₂(g) + Ca(OH)2 (aq) The product gas, C₂ H₂, is collected over water at a temperature of 20 °C and a pressure of 742.0 mm Hg. If the wet C₂H₂ gas formed occupies a volume of 9.02 L, the number of moles of CaC2 reacted was mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.
