Chapter 13, Problem 90QAP

Calcium carbide, ${\text{CaC}}_{\text{2}}$, reacts with water to produce acetylene gas, ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}$.

msp;  ${\text{CaC}}_{\text{2}}{\left(s\right)}_{+}{\text{2H}}_{\text{2}}\text{O}\left(l\right) {\text{C}}_{\text{2}}{\text{H}}_{\text{2}}\left(g\right)+\text{Ca}{\left(\text{OH}\right)}_{\text{2}}\left(s\right)$

at volume of acetylene at $\text{25 }°\text{C}$and $\text{1}.0\text{1}$atm is generated by the complete reaction of $\text{2}.\text{49 g}$of calcium carbide? What volume would this quantity of acetylene occupy at STP?
