Question

The rate of diffusion of hydrogen gas is three times faster than that of unknown gas what is the molar mass of unknown gas?

Answer 1

Answer:

Explanation:rate of diffusion =1/ root of molecular mass

so, 3r/ r= root of m/ root 2 (hydrogen h2 m.mass) after solving

9= m/2

m=18

Answer 2

Answer:

Let rate of diffusion of hydrogen be R1And rate of diffusion of helium be R2We know that, R1/R2=(M2/M1)^1/2R1=R2 (M2/M1)^1/2 =R2 (4/2)^1/2 =R2 (2)^1/2 =R2 × 1.41.°. R1=1.41 R2
