Molarity

A measure of the concentration of a solute in a solution, expressed as the number of moles of solute per liter of solution (mol/L).

Diluted

Refers to a solution that has had solvent added to decrease the concentration of solutes, making it less potent.

Molarity

A unit of concentration indicating the number of moles of a solute dissolved in one liter of solution, often used in chemical solutions for its precision.

Diluted

Refers to a solution that has had its concentration of solute reduced, typically by adding more solvent.
