Liquid methanol is fed to a space heater at a rate of 12.0 L/h and burned with excess air. The product gas is analyzed and the following dry-basis mole percentages are determined: CH3OH = 0.45%, CO2 = 9.03% and CO = 1.81%. (a) Draw and label a flowchart and verify that the system has zero degrees of freedom.  (b) Calculate the fractional conversion of methanol, the percentage excess air fed, and the mole fraction of water in the gas product
