A gas made up of homonuclear diatomic molecules escapes through a pinhole 0.936 times as fast as N2 gas. Write the chemical formula of the gas.

See explanation

Explanation:

Let the rate of diffusion of the unknown gas be x

Let the rate of diffusion of nitrogen be y

Let molecular mass of unknown gas be MX

Let molecular mass of nitrogen be My

Hence;

x/y = √My/MX

0.936/1 = √28/MX

(0.936/1)^2= 28/MX

MX= 28/0.876096

MX= 32 g/mol

MX is O2 gas
