Respuesta :
you would do the √molar mass B (neon) over √molar mass A (hydrogen)
√20/√2 = 3.16
√20/√2 = 3.16
The ratio of the average velocity of hydrogen molecules to that of neon atoms at the same temperature and pressure will be 3.16.
What is the average velocity?
The total displacement traveled by an object divided by the total time taken is the average velocity.
The average velocity of an object indicates the pace at which it will traverse a distance. The metric unit of speed is the meter per second.
The formula for the average velocity of a molecule is found as;
[tex]\rm v_{avg}= \[\sqrt{\dfrac{8RT}{\pi M}}\][/tex]
If all the given values are the same for the hydrogen molecules and neon atoms.
The velocity is inversly proportional to the square root of the mass;
[tex]R = \frac{\rm v_{avg}(H)}{\rm v_{avg}(Ne)} \\\\\ R=\frac{\sqrt{m_{Ne}} }{\sqrt{m_{H}} } \\\\ R=\frac{\sqrt{20} }{\sqrt{2} } \\\\ R=3.16[/tex]
Hence the ratio of the average velocity of hydrogen molecules to that of neon atoms at the same temperature and pressure will be 3.16.
