What is the amount of solute per given amount of solvent?

Concentration

Explanation:

Concentration is measure of the quantity of solute present in a given amount of solvent. Concentration can be measured in mol/dm³, g/m³ and other forms like molality, parts per million.

Concentration in mol/dm³(molarity) is a measure of the amount of moles of solute present in 1 dm³ of solvent while concentration in g/dm³ is the number of grams of solute present in 1 dm³ of solvent. These units of concentration can be converted to the other unit by using simple conversion methods.

molality refers to the amount of solute in 1 kg of solvent, while ppm is basically used for very dilute solutions.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
