Question:

Consider the combustion reaction between 25.0 mL of liquid methanol (Density = 0.850 g/ml) and 12.5 L of oxygen gas measured at STP. The products of the reaction are CO2 (g) and H2O (g). Calculate the volume of liquid H2O formed if the reaction goes to completion and you condense the water vapor.
