The volume of 1 kmol of a mixture of methane (CH4) and CO2 by a given temperature and a given pressure varies with the composition shown in the table:

Mole fraction methane	0	0.2	0.4	0.5	0.6	0.85	1.0
Volue (m3) of 1 kmol	0.09	0.18	0.21	0.22	0.23	0.25	0.255

1. Use this to find tha partial molar volume for methane and for CO2 when the mole fraction for methane is 0.6. (Make a sketch or a graph that show how you found the answer),

2. If you look away from the mixturevalues in the table and consider ideal mixture, what would the volume of the mixture with mole fraction 0,6 for methane be then?

Answers should be: 1: CO2 = 0.186 m3/kmol. CH4 = 0.26 m3/kmol.

2: 0.189 m3/kmol
