Molarity Formula
Molarity provides connection between moles of a solute and the volume of its solution. The definition provided serves as a tool for calculating molarity from the values of moles of solute and volume of solution. The molarity of a solution is calculated by taking the moles of solute and dividing by the liters of solution.
Molarity = $\frac{Moles\ of\ solute}{Liters\ of\ solution}$
Molarity is the tool we use to write an equivalence between moles of solute and volume of solution, from which appropriate conversion factors can be formed.
