Part A, B, and C please

Compute the specific gas constant for a gas which is composed by 70% oxygen and 30% nitrogen (in mass), mean molecular weight, and then compute the specific volume of this gas at p = 600 mb and T=-10C. (Note that I mb=1 hPa = 100 Pa; also give units to your answers.) Port A malm z n 23 28 M = 39,68 Answer: (1) R = (2) M = 30,68 ;a= What is the mean molecular weight and specific gas constant for the earth's atmosphere at 1000 mb (1 atmosphere), temperature of 15.0*C, and with vapor pressure of 6.0 mb? (Hint: compute separately the density of dry air and the density of water vapor. Then add the two to obtain the total density to be used in the equation of state to solve for R and then M). Part B 3 Answer: M= ; R= (a) What is the specific volume for a gas which is composed by, in mass, 65% nitrogen (M=28 kg kmol"'), 30% oxygen (M=32 kg kmol-!), and 5% helium (M-4 kg kmol!) at 2 p=800 mb and T= -10C?
