The natures of solvent as well as of solute are not the only criteria that should be considered to have an idea about the behaviors and properties of most of the substances in solution form. Rather there is very important role of concentration of solute in a solution.
Although there are so many units that are available in varied litterateurs that are used to express concentration of any solution. But among them, the most commonly used one is Molarity.
Molarity is defined as a ration of number of moles of solute that are dissolved in unit volume i.e. per liter of the solution.
Molarity is denoted by the symbol “M”.
Molarity can be formulated as:
Molarity= number of moles of solute/ volume of solution in liter on dm3

When two or more solutions of different concentration or strengths are mixed together then this mixing will yield another solution having a totally different strength as compare to the reacting solutions. Molarity is one of the most commonly employed units of concentration and it can be defined as the number of moles of solute that are contained in a liter of solution. In case of mixing of two solutions of different molarities that are in diverse amounts as well; their molarity is find out by a different way.
So in order to find out the fresh concentration of the solute, amount of the solute which is stated in term of moles which is simultaneously situated in the solution possesses the volume which is equal to the summation of two solutions that are mixed together. In lab practices, it rarely occurs that a homogenous solution is present. Most of the times, chemists have to deal with the mixture of solution. If their concentration is not accurately determined, then it will definitely yield to the wrong outcomes and all the research or other concerned workings will go in vain. Therefore, it is very essential to find out the correct concentration of a mixing in terms of molarity in order to make the results authentic.

In the field of chemistry, molarity is the most commonly used term to define the concentration of any chemicals or solutions. It is the unit of concentration which is widely used for making stock solutions, dilutions etc which are normally used for finding the purity and quality of any research sample or for different means. No matter where these molar solutions are used, it is very essential that there molarity should be calculated in a correct manner to make the result precise and calculations as robust as possible. Molarity is abbreviated by the symbol of M and it can be defined as the number of moles of solute that are dissolved per liter of a solution. Mole is one other term which is used in chemistry and refers to the ratio of mass in grams of solute and its molecular weight. So by the knowledge of volume of the final solution as well as the mass of solute which is dissolved in that solution, molarity of a solution can easily be calculated.

A lot of molarity calculators are available on internet for you. These make the users more free out of calculations of molarity. As a user you just have to enter the values and the molarity will be checked by the online molarity calculator (here). This is really very interesting to use an online calculator.
The main advantage behind the Molarity calculator is that the results are reliable. You need not be worried about the results. Human errors are negligible in the results concluded by the molarity calculator.
