Acetylene gas, C2H2(g), can be prepared by the reaction of calcium carbide with water:
CaC2(s)+2H2O(l)→Ca(OH)2(s)+C2H2(g)

Calculate the volume of C2H2 that is collected over water at 23 ∘C by the reaction of 0.752 g of CaC2 if the total pressure of the gas is 740 torr. (The vapor pressure of water is 21.07 torr) needs to be in L.
