A gaseous mixture consists of

10%N_(2),20%CO_(2),30%CO,20%H_(2)

and

20%O_(2)

(on a mass basis) at

260K

and

10MPa

. The mixture is contained in a piston-cylinder device and is heated at constant pressure until the temperature rises to

300K

. Determine (a) the constant-pressure specific heat, (b) the apparent molar mass, (c) the apparent gas constant, (d) the heat transfer during the process by treating the mixture as an ideal gas (in

kJ

) and (e) the heat transfer during the process by treating the mixture as a nonideal gas and using Amagat's law (in kJ).
