Molarity Formula
The formula to determine the Molarity of a solution is given as follows:
Molarity (M) = n / V
where,
“n” is the number of moles of the solute.
“V” is the volume of solution in liters.
Formula to calculate the Number of Moles of Solute
(n) = Mass of the solute / Molar mass of the solute
Molarity – Definition, Formula and Solved Examples
Molarity is defined as total number of moles of solute per litre of solution. It is represented by M. In chemistry, the molarity is one of the concentration units. The concentration of solutions can be expressed more effectively using measurements based on moles. The SI unit of Molarity is Mole.
A mole is an SI unit that measures the amount of a substance, where the amount of a substance is a measurement of the number of its elementary entities present in an object or sample. According to the definition, a mole contains exactly 6.022 × 1023 elementary entities, where 6.022 × 1023 is called Avogadro’s number (NA). Molarity is used to measure the concentration of a solution, where a concentrated solution is a solution with more solute and less solvent.
