Rate of diffusion of gases is directly proportional to partial pressure and inversely proportional to square root of molecular mass.
‌

R1

RX

=√‌

Mx

M1

(where R1= rate of diffusion of methane gas,
RX= rate of diffusion of X′ gas,
MX= molecular mass of ' X ' gas,
M1= molecular mass of methane gas)
As,
R1‌=2RX
‌

2RX

RX

‌=√‌

MX

16

2‌=√‌

MX

16

Squaring both sides,
4‌=‌

MX

16

∴MX‌=64.
