$$CaC_2+ H_2O → C_2H_2+ Ca(OH)_2$$

The reaction of calcium carbide and water produces acetylene gas $(C_2H_2)$ and calcium hydroxide.

What volume of $C_2H_2$ will form from 0.200 mol $CaC_2$ which reacts with an excess of water? Assume the gas will be at STP conditions.

A

$0.200 \ L$

B

$4.5 \ L$

C

$2.25 \ L$

D

$22.4 \ L$

E

$5.2 \ L$
