Problem- Consider the combustion reaction between 28.0mL of liquid methanol (density=0.850g/mL) and 14.0L 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.
Please show the entire work. I am thanking you in advance
