Chapter 5, Problem 5.92PAE
94 Mining engineers often have to deal with gases when planning for the excavation of coal. Some of these gases, including methane, can be captured and used as fuel to support the mining operation. For a particular mine, 2.4 g of CH4 is present for every 100.0 g of coal that is extracted. If 45.6% of the methane can be captured and the daily production of the mine is 580 metric tons of coal, how many moles of methane could be obtained per day?

An "ideal" fuel/air mixture in which both the fuel and the oxygen in the air are completely consumed is called the "stoichiometric" mixture. The stoichiometric mixture is usually specified as the ratio of the mass of air to the mass of a particular fuel. For example, if a fuel (for
example, natural gas, CH4) required 17.2 kg of air to precisely burn 1 kg of the fuel (that is, all the fuel burned and there was no oxygen left in the air afterwards) then the stoichiometric ratio for that fuel would be 17.2: 1.
Calculate the partial pressures of the natural gas and oxygen in the mixture based on the stoichiometric ratio given above at 293.15 K. The volume of the internal combustion engine is considered to be 2.500 L. The mass of the fuel is 160.0 g.
Mass fraction of oxygen in air is 23.1%.
Molar mass of natural gas is 16.043 g/mol.

The human body burns glucose (C6H₁2O6) for energy according to this chemical reaction:
C6H12O6 +60₂-6CO₂ + 6H₂O
The products of the reaction are carbon dioxide (CO₂) and water (H₂O).
Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500. mL of air,
which is typically enriched to 4% CO₂ and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight that is lost actually departs
his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.9 kg of carbon dioxide.
Calculate how many breaths it takes an average person to "exhale" 1.00 kg of fat. Round your answer to the nearest thousand.
You'll need to know that the density of CO₂ is 2.0 kg/m³.
