Molal Concentration (Noun)
Meaning
Concentration measured by the number of moles of solute per kilogram of solvent.
Classification
Nouns denoting attributes of people and objects.
Examples
- Molal concentration is used to express the concentration of solutions where the solute does not dissolve well in the solvent and temperature does not significantly affect the concentration.
- To prepare a solution of molal concentration 1, we would add 1 mole of the solute to 1 kilogram of the solvent.
- For gases and non-ideal solutions, the molal concentration cannot be converted directly into other units, because of varying gas molar volume or partial volumes.
- Calculating molal concentration can help chemists accurately mix a desired concentration for laboratory testing or practical use.
- Measuring the molal concentration allows the exact proportions of substances to be recorded when solutions with strong concentrations need precise mixture requirements.
