Question

Also we have a mixture for gas is hydrogen helium neon and nitrogen sealed in a container of -50 Celsius degree so imaginary pick one molecule and follow it around for some time and record speed we determine that on average a small chill travels with speed of approximately 1.9x10^3 km/h . Which molecule or atom did we pick up MM,g/mol Hydrogen 2.02 Helium 4.00 Neon 20.18 Nitrogen 28.01

Expert Solution

Step 1

From kinetic theory of gases, the root-mean-square velocity of a gas is given by the formula:
$v_{R M S} = \sqrt{\frac{3 R T}{M}} w h e r e v_{R M S} i s t h e r o o t - m e a n - s q u a r e v e l o c i t y o f a g a s, R i s t h e g a s c o n s \tan t = 8.314 J / m o l / K T i s t h e t e m p e r a t u r e, M i s t h e m o l a r m a s s$
