The molarity of a solution is the number of moles of solute per liter of solution. Molarity allows for easy dilution of a solution using the dilution formula where the initial concentration multiplied by the initial volume is equal to the final concentration multiplied by the final volume (M1V1=M2V2). Multiplying the molarity by the volume gives the total moles of the material, which can be diluted to any lower concentration.

**Formula**

**Molarity= [(% x d) / MW] x 10**

**Where,**

%=Weight Percentage,

d=Density,

MW=Molecular Weight.

**Molarity refers to:**

1) Number of moles of solute per litre of solution.

2) the number of moles of a solute dissolved in a liter of solvent. Note: be careful not to confuse molarity and molarity. Molarity is represented by a small "m," whereas molarity is represented by an upper case "M."

3) The number of moles of solute in q liter of solution.

__Example__:

Calculate the Molarity for the given details.

Weight percentage = 250

Density = 50

Molecular weight/Formula Weight = 25

__Solution__:

**Apply Formula:**

Molarity= [(% x d) / MW] x 10

**Molarity = 5000**
