Problem
1. Weighing of masses gives a mixture at 60?C, 225 kPa with 0.5 kg O2, 1.5 kg N2, and 0.5 kg CH4. Find the partial pressures of each component, the mixture specific volume (mass basis), mixture molecular weight, and the total volume.
2. A carbureted internal combustion engine is converted to run on methane gas (natural gas). The air-fuel ratio in the cylinder is to be 20:1 on a mass basis. How many moles of oxygen per mole of methane are there in the cylinder?
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.
