Question

molecule a is heavier than molecule b. assuming all other conditions are the same, which molecule will diffuse faster when suspended freely in a solution? molecule b will diffuse faster. molecule a will diffuse faster. they will diffuse at the same rate. if they have mass, they will not be able to diffuse.

Explanation:

According to Graham's law of diffusion, the rate of diffusion of a gas is inversely proportional to the square root of its molar mass. Heavier molecules (with higher molar mass) diffuse more slowly. Since Molecule A is heavier than Molecule B, Molecule B will diffuse faster.

Answer:

Molecule B will diffuse faster.
