Calculadora de Molaridad

Calcula la molaridad (M) de una solución a partir de los moles de soluto y el volumen.

Formula
Molarity (M) = moles of solute / liters of solution
What is This Tool?

Molarity (M) measures the concentration of a solution as the number of moles of solute per liter of solution. It is the most commonly used unit of concentration in chemistry, essential for stoichiometry, titrations, and preparing lab solutions.

Formula
M = n / V Where: M = molarity (mol/L) n = moles of solute (mol) V = volume of solution (L)
Worked Examples

1. Dissolving NaCl

Given: 0.5 mol NaCl in 0.25 L of solution

M = 0.5 mol / 0.25 L

M = 2.0 mol/L

Result: 2.0 M

2. Dilute acid solution

Given: 0.1 mol HCl in 2.0 L of solution

M = 0.1 mol / 2.0 L

M = 0.05 mol/L

Result: 0.05 M

3. Concentrated sugar water

Given: 3.0 mol glucose in 0.5 L

M = 3.0 mol / 0.5 L

M = 6.0 mol/L

Result: 6.0 M
