Concentration is an expression of how much solute is dissolved in a solvent in a chemical solution. There are multiple units of concentration. Which unit you use depends on how you intend to use the chemical solution. The most common units are molarity, molality, normality, mass percent, volume percent, and mole fraction.
The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution. A concentrated solution is one that has a relatively large amount of dissolved solute.
Mass/volume percent (m/v)% concentration. The mass/volume percent concentration expresses the mass units of solute in a hundred volume units of solution. Mathematical form of m/v % is: Mass/volume (%) = mass of solute (g) volume of solution (mL) × 100.
In chemistry, the concentration of a solution is the quantity of a solute that is contained in a particular quantity of solvent or solution. Knowing the concentration of solutes is important in controlling the stoichiometry of reactants for solution reactions.
In chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. The standard formula is C = m/V, where C is the concentration, m is the mass of the solute dissolved, and V is the total volume of the solution.
How to Calculate Units of Concentration. Once you have identified the solute and solvent in a solution, you are ready to determine its concentration. Concentration may be expressed several different ways, using percent composition by mass, volume percent, mole fraction, molarity, molality, or normality. Percent Composition by Mass (%)
The concentration of a chemical solution refers to the amount of solute that is dissolved in a solvent. Although it’s common to think of a solute as a solid that is added to a solvent (e.g., adding table salt to water), the solute could exist in another phase.
The concentration calculator is a tool for converting the molarity into percentage concentration (or vice versa) with a known molar mass of the dissolved substance and the density of the solution. In addition, you can calculate the mass of the substance per 100 g of water if the percentage concentration is known.

Concentrations of Solutions. There are a number of ways to express the relative amounts of solute and solvent in a solution. This page describes calculations for four different units used to express concentration: Percent Composition (by mass) Molarity. Molality. Mole Fraction. Percent Composition (by mass)
