A chemical solution is a homogeneous mixture of one or more substances called “solutes” in another substance called “solvent”. The concentration of a solution is the amount of solute that is dissolved in a certain amount or solvent or solution.
There are different units to represent the concentration of a solution, among them there are the molarity (M), defined as the moles of solute present in 1 L of solution; molality, (m) defined as the moles of solute dissolved in 1 kg of solvent; and percentage by mass (%m), which represents the grams of solute dissolved in 100 g of solution.
