A Wingbarton hydrocarbon bomb explodes in the dry air near an Orsat analyzer. A slightly injured but quick-witted technician quickly carries out a dry gas analysis in the shattered remains of the laboratory to produce the following results: 2.80% CO2, 0.500% CO, 16.2% O2, and 80.5% N2: Determine
a. The fuel model ðCnHmÞ and probable name of the mysterious hydrocarbon explosive used in the Wingbarton bomb.
b. The mass percentage composition of the carbon and hydrogen in the bomb.
c. The percentage of excess air available in the laboratory when the bomb exploded.
d. The dew point temperature in the lab after the bomb exploded (assume atmospheric pressure).
