In a gas mixture if molecular weights of all the species are equal tha...
Explanation: Average molar mass of the mixture=M(x1+x2+………+ xn)=M
(x1+x2+………+ xn=1)
Mass average velocity=Σuiρi/ρ=uiPui/P
Molar average velocity=Σciui/c=ρuiPi/P (P=cRT).
(x1+x2+………+ xn=1)
Mass average velocity=Σuiρi/ρ=uiPui/P
Molar average velocity=Σciui/c=ρuiPi/P (P=cRT).

In a gas mixture if molecular weights of all the species are equal tha...
Explanation:
Mass Average Velocity:
- Mass average velocity is the average velocity of all the molecules in a gas mixture taking into account their mass.
- In a gas mixture where molecular weights of all the species are equal, the mass average velocity will be the same for all the species since they have equal masses.
Molar Average Velocity:
- Molar average velocity is the average velocity of all the molecules in a gas mixture taking into account their molar masses.
- In a gas mixture where molecular weights of all the species are equal, the molar average velocity will also be the same for all the species since they have equal molar masses.
Conclusion:
- Since the molecular weights of all the species in the gas mixture are equal, both the mass average velocity and the molar average velocity will have the same value for all the species.
- Therefore, in this scenario, both the mass average velocity and the molar average velocity will have the same value.
