Two containers A and B have the same volume. Container 'A' contains 5 mole oxygen gas. Container 'B' contains 3 moles He gas and 2 mole CH_4 gas. Both the containers are separately kept in vaccum at the same temperature. Both the containers have very small orifices of the same area through which the gases leak out. The rate of diffusion of O_2 is how many times the rate of diffusion of He and CH_4 mixture

1.	Two containers A and B have the same volume. Container 'A' contains 5 mole oxygen gas. Container 'B' contains 3 moles He gas and 2 mole CH_4 gas. Both the containers are separately kept in vaccum at the same temperature. Both the containers have very small orifices of the same area through which the gases leak out. The rate of diffusion of O_2 is how many times the rate of diffusion of He and CH_4 mixture
Answer» `sqrt((8.8)/(32))` `sqrt((7)/(32))` `3/2 sqrt((8.8)/(32))` `sqrt((32)/(8.8))` Solution :`M_("MIX") = (3 xx 4 + 2 xx 16)/(5) = 44/5 = 8.8`. `(r_(O_2))/(r_("mix")) = sqrt((M_("mix.))/(32)) = sqrt((8.8)/(32))`.
