A 9.32 g sample of 3-ethyl-2,4-dimethylpentane (formula C9H20), is mixed with 7.77 atm of O2 in a 8.82 L combustion chamber at 426.77 °C. The combustion reaction to CO2 and H2O is initiated and the vessel is cooled back to 426.77 °C. Report all answers to two decimal places in standard notation (i.e. 1.23 atm).
2. What is PO2 (in atm) in the combustion chamber after the reaction goes to completion?
