Question

Statement: The rate of diffusion of a gas is inversely proportional to both, square root of density and molecular mass.

If the given statement is true enter 1, else enter 0.

Answer 1

Graham's law states that the rate of diffusion of a gas is inversely proportional to the square root of its molecular weight. n the same conditions of temperature and pressure, the molar mass is proportional to the mass density. Therefore the rate of diffusion of different gases is inversely proportional to the square root of their mass densities.

$r\alpha \frac{1}{\sqrt{d}}$ and $r\alpha \frac{1}{\sqrt{M}}$

Hence, the given statement is $\text{true}$ and correct entry is 1
