84. heavy water, d2o (molar mass = 20.03 g mol–1), can be separated from ordinary water, h2o (molar mass = 18.01), as a result of the difference in the relative rates of diffusion of the molecules in the gas phase. calculate the relative rates of diffusion of h2o and d2o.

relative rate of diffusion is 1.05

Explanation:

According to Graham's law of difussion:

Rate of diffusion is inversely proportional to the square root of molecular weight of a molecule.

For two given molecules:

The given molecules are

Water = 18.01

Heavy water =20.03

Thus the relative rate of diffusion will be:

catya your not at all which answer i've seen you do this on another question!

it is b that is the answer.
