Absorbance is unitless by definition, this is the fraction of light absorbed.
Solute concentration will have mol/L units, so it is not unitless.
i/i0 (ratio of emergent to incident intensity) is similar to absorbance, and the units will cancel out, making this unitless.
Path length will have a unit in millimeters or centimeters, so it is not unitless.

Therefore the unitless quantitites are absorbance and intensity ratio.

A high concentration of water has ____________ dissolved particles than a low water concentration.
N76 [4]

A high concentration of water has <u>fewer</u> dissolved particles than a low water concentration.

Most cell membranes are not as easily permeable to many dissolved compounds as water is. There is a quick and constant flow of water. From one area with less dissolved matter to another with more, water transports NET. Or, if you want, from an area with a lot of water to one with little water. The terms isotonic, hypotonic, and hypertonic refer to the concentration of dissolved material. In a medium, such as the extracellular fluid, every distinct material has a concentration gradient that is unique from the gradients of other substances. Every substance will diffuse in line with that gradient as well.
