The volume of 1 kmol of a mixture of methane (CH4) and CO2 at a certain temperature and a certain pressure varies with composition as shown in the table. Mole fraction methane 0; 0,2; 0,4; 0,5; 0,6; 0,85; 1,0; Volume (m3) of 1 kmol 0,09; 0,18; 0,21; 0,22; 0,23; 0,25; 0,255; - Use this to determine the partial molal volume for methane and for CO2 at the methane mole fraction of 0,6. (Make a sketch or graph that shows how you achieve the result.) - If the mixture values of the table are neglected and the mixture is assumed ideal, what is then the volume of the mixture at the methane mole fraction of 0,6?
