Problem

We have prepared acetylene, C2H2 (g), in class 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 28.0°C by the reaction of 1.60 g CaC 2 (MM = 64.10g/mol) if the total pressure was 748.0 mmHg. The vapor pressure of water at 28.0°C is 28.3 mmHg. 

a) 0.651 L

b) 0.424 L

c) 0.384 L

d) 4.57 L

e) 8.03 L
