For common solutes, use values such as 58.44 for NaCl or 180.16 for glucose.<\/li>\n<li>If you chose the mole method, enter the <strong>Solute Amount (Moles)<\/strong> directly.<\/li>\n<li>Enter the <strong>Solvent Mass<\/strong> and select its unit. This must be the mass of the solvent alone (for example, the water), not the total mass of the solution.<\/li>\n<li>Read the results: <strong>Molality<\/strong> in mol\/kg, along with the calculated <strong>Moles of Solute<\/strong> and the <strong>Solvent Mass<\/strong> converted to kilograms.<\/li>\n<\/ol>\n<h2>What Is Molality?<\/h2>\n<p>Molality (symbol \\(b\\), sometimes written \\(m\\)) is a measure of the concentration of a solution: it tells you how many moles of solute are dissolved in each kilogram of solvent. Unlike molarity, which is expressed per liter of <em>solution<\/em>, molality is based purely on the <em>mass<\/em> of the solvent. This makes it independent of temperature and pressure, because mass does not change when a liquid expands or contracts.<\/p>\n<p>A 1 mol\/kg solution (often called \"1 molal\" or \"1 m\") contains one mole of solute per kilogram of solvent. In the example above, 1 mole of NaCl in 0.5 kg of water gives 2 mol\/kg \u2014 twice as concentrated as a 1 m solution.<\/p>\n<p>Molality is especially important in fields where temperature varies. It appears in the equations for boiling point elevation and freezing point depression (colligative properties), in cryoscopic and ebullioscopic measurements, and in thermodynamic relations involving solvent activity. For laboratory work at constant temperature, however, molarity or mass percent is often more convenient; see the <a href=\"https:\/\/wpcalc.com\/en\/chemistry\/c1v1-c2v2\/\">C1V1 = C2V2 dilution calculator<\/a> for concentration-based calculations.<\/p>\n<p>Because molality is defined per kilogram of <em>solvent<\/em>, the same amounts of solute and solvent always give the same molality, no matter the density of the liquid or the temperature of the lab. To go the other way \u2014 from a weighed sample to a number of particles \u2014 you may also find the <a href=\"https:\/\/wpcalc.com\/en\/chemistry\/convert-atoms-to-moles\/\">atoms to moles converter<\/a> useful.<\/p>\n<h2>Assumptions, Limitations and Tips<\/h2>\n<ul>\n<li><strong>Solvent mass, not solution mass.<\/strong> The most common mistake is entering the total mass of the solution. If you only know the solution mass, subtract the solute mass first: \\(m_{\\text{solvent}} = m_{\\text{solution}} - m_{\\text{solute}}\\).<\/li>\n<li><strong>Molar mass must be accurate.<\/strong> The moles of solute depend directly on the molar mass you enter. For hydrated salts (e.g. CuSO<sub>4<\/sub>\u00b75H<sub>2<\/sub>O) include the water of crystallization in the molar mass.<\/li>\n<li><strong>Units are converted automatically.<\/strong> Masses can be entered in grams, milligrams, kilograms, pounds or ounces; the calculator converts everything to mol\/kg internally.<\/li>\n<li><strong>Molality vs. molarity.<\/strong> Do not confuse the two: a 1 m (molal) solution and a 1 M (molar) solution generally contain different amounts of solute. Molality uses solvent mass; molarity uses the final volume of the solution.<\/li>\n<li><strong>Real solutions.<\/strong> Molality is a purely stoichiometric quantity. It says nothing about whether the solute dissociates (NaCl forms ions in water) or how the particles behave; for colligative-property calculations, account for the van 't Hoff factor separately.<\/li>\n<li><strong>Positive values only.<\/strong> The calculator requires positive solute and solvent amounts; enter zero masses to see an error message rather than a meaningless result.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Calculate the molality of a solution in mol\/kg.
