The boiler in an apartment building uses propane (CaHe) to heat water that circulates throughout the building as steam. 1.00 m'/s of propane gas at 25°C and 1 atm is combusted with 10% excess air at 25°C and 1 atm. After all of the propane is combusted, the product gas contains a 10.0:1 molar ratio of CO2 to CO and leaves the boiler at 25°C. Heat from the boiler is transferred to a pure water stream at 50°C and 1.0 bar, which is converted into saturated steam at 20 bar, with no heat lost to the surroundings in the process.

A 0.2m3 rigid tank initially contains pure oxygen gas (02) at 20°C and 1000 kPa. The tank containing the oxygen is put on a scale to measure its mass. The initial mass is recorded as 110.4 kg. Nitrogen gas is injected isothermally into the tank until the scale reads 121.0 kg. The molar mass of oxygen is 32kg/kmol and the molar mass of nitrogen is 28 kg/kmol. Assuming that the gases behave ideally, answer the following questions: a) What is the mass of the empty tank? b) What is the composition of the final mixture on a mole basis? c) What is the final pressure of the tank? d) The critical temperature and pressure of oxygen are 154.6K and 49.8atm. Based on these properties, comment on the appropriateness of using the ideal gas law in part a)
