Question

A vessel of volume 100ml contains 10%O2 90%unknown gas.The gas defusing in 86second through a small vessel.If pure oxygen under the same condition diffuses in 75 second find the molecular mass of unknown gas.
​

Answer 1

Answer:

Let M2 and M1 Be the molecular weight of gases,

Molecular weight of gases = 32 .

Molecular weight of gas mixture

= ( 10×32 + 90×m) / 100 .

= 3.2 + 9×m .

we know that ,

r oxygen/ r mixture= √ m mixture/ m oxygen

= 86 /75 = √ 3.2 + 0.9 × m / 32

= m = 46.75 gm
