Question 2.8: Compressed air is commonly used to power a large variety of power tools. Lowe's sells an air compressor that can fill an 8-gallon tank to 160 psi. At a temperature of 70°F, determine the mass of the air inside a full 8-gallon tank. Let Patm = 14.7 psi. a) Use the ideal gas law (you will need to do a lot of unit conversions for this). [0.429 kg] b) Find the compressibility factor. How far off is your analysis above? [0.99]
