At the critical point for carbon dioxide, the substance is very far from being an ideal gas. Prove this statement by calculating the density of an ideal gas in g/cm3 at the conditions of the critical point and comparing it with the experimental value. Compute the experimental value from the fact that a mole of CO2 at its critical point occupies 94 cm3.

For ethane at 298.15 K, B = -186 cm³mol-¹ and C= 1.06x104 cm'mol². Use the formula B PVm = RT [1 1+ + Vm V2 m to calculate the pressure of 28.8 g of ethane in a 999 cm³ container at 298.15 K and the amount of atm in which it is far from the ideal value.
A gas mixture contains 4.5 mol Br, and 33.1 mol F,. (a) Compute the mole fraction of Br, in the mixture. (b) The mixture is heated above 150°C and starts to react to give BrFs: Br2(g) + 5 F2(g) –→ 2 BrF;(g) At a certain point in the reaction, 2.2 mol BrF5 is present. Determine the mole fraction of Br2 in the mixture at that point.
