Consider the following unbalanced equation: C2H5OH(g) + O2(g) → CO2(g) + H2O(l)

1.55 g of ethanol reacts with 10.0 g of oxygen. What is the total volume of gas present (in L) after the reaction is complete, assuming the reaction takes place at 1.00 atm and 25oC?
A) 0.572 L
B) 9.29 L
C) 4.11 L
D) 6.82 L
E) 1.65 L

You will need to determine the limiting reagent, then calculate the volume of CO2 formed as well as the volume of the non-limiting reagent present at the end of the reaction. The apply PV = nRT and determine the total volume at the conditions listed. Post your work if you get stuck.
