Let 4 moles of methanol (liquid) combust in 3 moles of gaseousoxygen to form gaseous carbon dioxide and water vapor. Suppose thisoccurs in a chamber of fixed volume and fixed temperature. If theoriginal pressure is 1.0 atm, what is the final pressure in thechamber. Express your answer in atm. Enter only a numerical value,do not enter units. Assume liquids take up negligible volume.
