It doesn't. Ever since it was a child it has been a free spirit. It's parents expected it to depend on at least one of the two, but the diffusion coefficient just wanted to dance.

The diffusion coefficient is influenced by the size and shape of the solute molecule, as well as its interaction with the solvent molecules. Smaller molecules with weaker interactions tend to have higher diffusion coefficients compared to larger molecules with stronger interactions, which leads to slower diffusion. Additionally, temperature and viscosity of the solvent also affect the diffusion coefficient.

Is simple diffusion the net diffusion of a solvent?
no
Why is it that the greater the density of the solvent the slower the diffusion?
Greater solvent density means more particles in a given volume, leading to more collisions and interactions between solvent particles and solute molecules, hindering their movement and slowing down diffusion. This increased interaction and crowding restrict the movement of solute molecules, making diffusion slower in denser solvents.
Water dissolves a wide variety of substances. Therefore it is a?
universal solvent, meaning that it has the ability to dissolve many different types of solutes. This is due to its unique molecular structure and polarity, allowing it to form hydrogen bonds with other molecules. Water's solvent properties are essential for numerous biological and chemical processes to occur in our everyday lives.
How does the molecular weight of a solute substance affect the evaporation rate of a solvent?
Generally, a solute substance with a higher molecular weight will decrease the evaporation rate of a solvent. This is because larger molecules have stronger intermolecular forces, which hinders their ability to escape into the gas phase. As a result, the presence of high molecular weight solutes can lower the overall rate of evaporation of the solvent.
What properties of of a solute and solvent identify it as a solution?

How do you find the diffusion coefficient?
It is possible to calculate the diffusion coefficient of a liquid. You would set up a liquid-liquid diffusion coefficient sample. Use the variables W for solvent molecular weight, F for?æsolvent association factor, V for solvent viscosity, M for solvent molal volume, and T for system temperature.The equation you use is D(A,B) = [7.4T (FW) ^0.5]/ [V (M^0.6) * (10^8)].?æ
Is simple diffusion the net diffusion of a solvent?
no
How do you describe the dissolving process as a result of random molecular motion?
In the dissolving process, the solute particles break apart and disperse into the solvent due to the random motion of molecules. This motion causes collisions between solute and solvent molecules, leading to a gradual mixing at the molecular level until the solute is evenly distributed throughout the solvent.
Is osmosis also a type of diffusion?
NO, They are very different, just opposite of each other Osmosis is when a solvent (like water) moves through a semi-permeable membrane, from a solution of low concentration, to a solution with high concentration. Diffusion is the movement of molecules in a solvent, from a region of higher concentration to one of lower concentration by random molecular motion.
What happens to an solute?
In a solution, a solute is the substance that is dissolved in the solvent. The solute particles disperse evenly throughout the solvent due to random molecular motion. This results in a homogeneous mixture with uniform properties.
How is osmosis realted to diffusion?
Osmosis is related to diffusion by having something diffuse through a solvent
What is the diffusion of water?
its osmosis Osmosis is not the same as diffusion of water. Diffusion of water is just diffusion like with any other substance: the particles spreading, making a homogeneous distribution. Osmosis involves a semipermeabel membrane, where water goes from low solvent concentration to high solvent concentration.

Compare and contrast between osmosis and facilitated diffusion?
Osmosis is when a solvent moves from a lower concentration to a higher concentration. Facilitated diffusion is when a solvent moves down the concentration gradient through carrier molecules.
Why is it that the greater the density of the solvent the slower the diffusion?
Greater solvent density means more particles in a given volume, leading to more collisions and interactions between solvent particles and solute molecules, hindering their movement and slowing down diffusion. This increased interaction and crowding restrict the movement of solute molecules, making diffusion slower in denser solvents.
What is the relationship between penetration coefficient and relative miscibility of alcohols?
The penetration coefficient is a measure of how well a solute (such as alcohol) can permeate through a solvent. The relative miscibility of alcohols refers to how well they mix or dissolve in a particular solvent. Generally, alcohols with higher penetration coefficients tend to have better relative miscibility in a solvent, indicating they can permeate through the solvent more easily.
