Find the ratio of the mean speed of hydrogen molecules to the mean speed of nytrogen molecules in a sample containing a mixture of the two gases.

Explanation

We know,
`V_avg = (sqrt(8RT))/(sqrt(pi M))`
`((V_(avg)) H_2)/((V_(avg))N_2) = ((sqrt(8 xx RT))/(sqrt(pi xx 2))) xx((sqrt(pi xx 28))/(sqrt(8RT)))`
` =(sqrt (28 / 2)) = (sqrt (14))=3.74`
