PartA A1. A mixture of three gases has the following analysis by mass 25% O, 43% CO, 32% N, The mixture has a volume of 0.8 m23 when its temperature and pressure are 30 °C and 1.25 bar respectively (...
A mixture of gases has the composition given in Table 1. It has a total mass of 3.46 kg, and has an initial volume and temperature of 1.273 m3 and 300 K respectively. The mixture undergoes polytropic compression to a final volume of 0.5 m3. The polytropic index for this process is known to be 1.2.

5. a) The composition of a mixture of nitrogen and carbon dioxide gases is 30%-N, and 70%- CO2 by mole fraction. What is the mass fraction of the nitrogen constituent?b) Nitrogen (N2) at 150 kPa, 40°C occupies a closed, rigid container having a volume of 1 m3. If 2 kg of oxygen (O2) is added to the container, what is the molar analysis of the resulting mixture? If the temperature remains constant, what is the pressure of the mixture, in...
