Acetylene gas, C2H2(g), can be prepared by the reaction of calcium carbide with water:
CaC2(s) + 2 H2O(l) → Ca(OH)2(s) + C2H2(g)
Calculate the volume of C2H2 that is collected over water at 23 oC by reaction of 1.53 g of CaC2 if the total pressure of the gas is 753 torr. (The vapor pressure of water is 21.07 torr.)
