the rate of diffusion of gas having molecules mass 4 times that ouch4 is 50 cc. the rate of diffusion of mithane is??​

The rate of diffusion of methane is 100 cc.

Explanation:

Graham's law states that the rate of diffusion of a gas is inversely proportional to the square root of the molar mass of the gas. The equation for this follows:

      .....(1)

where M is the molar mass of the gas

We are given:

Since the molar mass of methane = 16 g/mol

Using equation 1:

Putting values in above equation, we get:

Hence, the rate of diffusion of methane is 100 cc.

since electrons are negative the answer is neagtaive
