The Molarity to Molality Calculator is a valuable tool used in chemistry to convert molarity to molality. Molarity (M) represents the concentration of a solute in a solution, measured in moles per liter (mol/L), while molality (m) denotes the concentration in moles of solute per kilogram of solvent (mol/kg). This conversion is crucial for various chemical calculations, especially in laboratory settings and industrial processes.
Formula of Molarity to Molality Calculator
The formula used by the Molarity to Molality Calculator is:
m = M / (Molar mass of solute * Density of solvent in kg/L)
Where:
- M is the molarity of the solution (in moles per liter, mol/L).
- Molar mass of solute is the mass of the solute in grams per mole (g/mol).
- Density of solvent is the density of the solvent in kilograms per liter (kg/L).

Example of Molarity to Molality Calculator
Let's consider an example to illustrate how the Molarity to Molality Calculator works:
Suppose we have a solution with a molarity (M) of 2.5 mol/L, a molar mass of solute of 60 g/mol, and a density of solvent of 1.2 kg/L. To find the corresponding molality (m), we can use the formula:
m = 2.5 / (60 * 1.2)
Calculating this, we find that the molality (m) of the solution is approximately 0.034 mol/kg.
Most Common FAQs
Answer: Molarity (M) measures the concentration of a solute in a solution in terms of moles per liter of solution, while molality (m) measures the concentration in terms of moles of solute per kilogram of solvent. Molarity depends on the volume of the solution, whereas molality is independent of temperature and pressure changes.
Answer: Converting between molarity and molality is essential for various chemical calculations, such as determining colligative properties, osmotic pressure, and reaction kinetics. It allows chemists to compare concentrations under different conditions and ensures accurate measurements in experimental setups.
Answer: Yes, the calculator can be used for any solvent-solute combination as long as the input values for molarity, molar mass of solute, and density of solvent are accurate and applicable to the specific solution being analyzed.
