Question

Equal volumes of H2 and He are inserted in the same vessel. The pressure exerted by H2 and He are in the ratio: ​

Answer 1

Answer:

1;2

Explanation:

the moleular weight of he take it as 4 and hydrogen 2 now ratio is h2;he=1;2

Answer 2

Answer

The masses of hydrogen and helium gases in the vessels are equal.

This means that the product of the number of molecules and the mass of a molecule must be same for H2 and He gases.

Since molecular masses of H2  and He are in the ratio 1:2, their number of molecules nH  and nHe  in the vessels must be in the reverse ratio, that is,  

nH:nHe= 2:1.

Hope this helps you.
