Find the dew point of products and mass of water condensed

Question

Problem

1. A fuel, C_xH_y, is burned with dry air, and the product composition is measured on a dry mole basis to be 9.6% CO₂, 7.3% O₂, and 83.1% N₂. Find the fuel composition (x/y) and the percent theoretical air used.

2. In an engine, liquid octane and ethanol, mole ratio 9:1, and stoichiometric air are taken in at 298 K, 100 kPa. After complete combustion, the products run out of the exhaust system, where they are cooled to 10^oC. Find the dew point of the products and the mass of water condensed per kilogram of fuel mixture.

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
