Acetylene gas, C2H2 (g), can be prepared by the reaction of calcium carbide with water: CaC2 (s)

Question:

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 by reaction of 1.524 g of CaC2 if the total pressure of the gas is 753 torr. (The vapor pressure of water is tabulated in Appendix B.)
