Consider the combustion reaction between 30.0mL of liquid methanol ( density = 0.850 g/mL) and 15.0L of oxygen gas measured at STP. The products of the reaction are CO2 and H2O. Please use these numbers and EXPLAIN. Calculate the VOLUME (mL) of liquid H2O formed if the reaction goes to completion and you condense the water vapor.
