Calculate the volume (in liters) of acetylene produced at 29 °C and 684 mmHg from 0.026 mol CaC2 and excess H2O.

CaC2 (s) + 2 H2O (l)  Ca(OH)2 (aq) + C2H2 (g)


Step 1: Calculate moles of C2H2

0.026 mol CaC2(1 mol C2H21 mol CaC2)=0.026 mol C2H2


Step 2: Calculate volume of C2H2

P should be in atm, use 1 atm = 760 mmHg
