All of the factors you listed can affect the rate of diffusion:
I. **Mass**: The mass of the particles can affect the rate of diffusion. Heavier particles will move more slowly and so will have a slower rate of diffusion. Smaller particles, on the other hand, will diffuse faster because they can move faster
II. **Density**: The density of the medium through which diffusion occurs can also affect the rate of diffusion. If the medium is very dense or viscous, then the particles will have a harder time diffusing through it
III. **Temperature**: The rate of diffusion is also affected by temperature. As temperature increases, the kinetic energy associated with each particle also increases. As a result, particles will move faster. If they can move faster, then they can also diffuse faster.
IV. **Nature of Substance**: The nature of the substance, including its size and charge, can affect how easily it diffuses. For example, smaller, nonpolar molecules diffuse more easily than larger, polar molecules.
So, in summary, the mass, density, temperature, and nature of the substance all play a role in determining the rate of diffusion.

From graham's law of diffusion which state that the rate of diffusion of gases is inversely proportional to the square root of its density at constant temperature and pressure
Molar mass=2xvapour density
Therefore diffusion depend on the mass, density and nature of the substance
