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.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
