An international espionage agent uses a computerized pocketsized Orsat apparatus to grab and analyze a dry sample of the exhaust gases from the new air-breathing, hydrocarbon-burning, Blood-Sucker guided missile. The Orsat readout is 6.20% CO2, 2.10% CO, 9.90% O2, and 81.8% N2. Determine
a. The fuel model CnHm and probable name of the BloodSucker's fuel.
b. The percentages of carbon and hydrogen by mass in the fuel.
c. The mass fuel/air ratio used by the missile.
