In the past, acetylene C2H2 was produced by reacting calcium carbide with water according to the following chemical equation:
CaC2 + 2 H2O → Ca(OH)2 + C2H2
What would be the volume of acetylene gas produced at 25 °C and 0.950 atm by the reaction of 128 g of calcium carbide and 45.0 g of water?
a. 45.2 L
b. 39.2 L
c. 32.2 L
d. 12.2 L
e. 49.2 L
