Q.1. Moles of H_2  = ((10)/2) = 5  N_2  = ((50)/(28)) ≈ 1.786  CO_2  = ((40)/(44)) ≈ 0.9  Average Molecular weight  = ((100)/(5 + ((25)/(14)) + ((10)/(11)))) ≈ 12.9958  Q.2. Moles of N_2  = ((4000)/(28)) = ((1000)/7)  Moles of CO_2  = ((6000)/(44)) = ((1500)/(11))  Total number of moles = ((21500)/(77))  Mole fraction of N_2  = ((1000)/7)×((77)/(21500))  ≈ 0.512  Mole fraction of CO_2  = ((1500)/(11))×((77)/(21500))  ≈ 0.488  Average molecular weight  = 10000×((77)/(21500)) ≈ 35.814  Partial pressure of N_2  = 0.512 × 4 bar  = 2.048 bar  Partial pressure of CO_2  = 0.488 × 4 bar  = 1.952 bar
