Rate of diffusion is inversely proportional to square root of molecular mass
R.d of CH4=2×R.d of X
Molecular mass of CH4=16
M.mass of X=?
2×R.d of x/R.d of x=square root of x/16
sending the root to left side it becomes square of 2 giving 4
4=x/16
X=16×4=64
molecular mass of X will be 64
R.d of CH4=2×R.d of X
Molecular mass of CH4=16
M.mass of X=?
2×R.d of x/R.d of x=square root of x/16
sending the root to left side it becomes square of 2 giving 4
4=x/16
X=16×4=64
molecular mass of X will be 64

Answer:
64
Explanation:
Let rate of diffusion of gas x, r1 = a
Therefore, rate of diffusion of methane,r2 = 2 a
According to Graham's Law of Diffusion
r1/r2= √ M2/M1.
M1 = Molecular mass of gas
M2 = Molecular mass of Methane= 16g.Therefore,
a/2a=√16/M2
Squaring both the sides,
1/4=16/M2 or,
M2 = 16×4=64 g
