What is the formula for calculating the molarity of a solution?

Molarity is a concentration unit that represents the number of moles of solute present in one liter of solution. The correct formula for calculating molarity is derived from this definition: it expresses the relationship between the amount of solute (in moles) and the volume of the solution (in liters). Therefore, the formula for molarity is formulated as the number of moles of solute divided by the volume of the solution in liters.

Using this formula, if you know the number of moles of a substance and the total volume of the solution, you can easily calculate how concentrated the solution is, which plays a crucial role in various chemical calculations and reactions. This understanding is fundamental in both theoretical and practical applications of chemistry, such as preparing solutions, diluting concentrations, and stoichiometry in chemical reactions.
