Title: Average velocities of Nytrogen and Hydrogen
Post by: Dhamnekar Winod on October 07, 2020, 09:26:35 AM
Hello,

What is the average velocity of a molecule of Nytrogen N2 at 300 K and that of molecule of Hydrogen H2 at the same temperature?

  My answer: Average velocity of N2 is 15.061 km/s and for hydrogen H2 it is 99.886 km/s. I used the formula average speed =square root of {8RT/M}, where T= temperature, R=gas constant, M=molar mass of gas.

Are these answers correct?

By the way, how can i use chemical equation package  and latex for math symbols in this forum?

 I want to make changes in my both answers:

Average velocity of molecule of Nytrogen N2=476.29 m/s and that of molecule of Hydrogen H2=1782.11 m/s

Here is the correct formula for the average speed of gas molecule. (http://[attachment%20id=ave%20speed%20of%20n2o2(1)edited.png%20msg=2655])

How can i edit or delete my post?

hi

you are talking about  the average velocity of a molecule of Nytrogen N2 at 300 K and that of molecule of Hydrogen H2 at the same temperature. please once you try with the basics. you can google more about it.
