Definition of molal in English:

molal

adjective ˈməʊləlˈmoʊləl

Chemistry

(of a solution) containing one mole of solute per kilogram of solvent.
〔化〕（溶液）摩尔（浓度）的，克分子的
Example sentencesExamples
- As such a one molal solution has one mole dissolved in 2.205 lb of solution.
- The osmolal concentration of TEG and MG were calculated from the dependence of their osmotic pressure on molal concentration.
- Calibration of the instruments was carried out with 0.1, 0.3, 0.5, 0.7, and 0.9 molal NaCl solutions of known water potential at 25°C.
- The section on the interconversion of molal and molar solutions needs to be reworded.
- If 1kg of solvent has two moles of solute dissolved in it than it is a 2 molal solution.

Derivatives

molality

noun məˈlalɪti

Chemistry

Instead of dealing with the volume of the solution or solvent, molality is concerned with the mass of solution or solvent.
Example sentencesExamples
- If the solvent used is water the molarity and the molality are essentially the same.
- The latter three properties are directly proportional to the molality of the dissolved solute, which is defined as the number of moles of solute per kilogram of solvent.
- It may be shown that the use of molality corrects for molecular volumes, but not for excluded volumes.
- An electrolyte's ionic strength is half of the total obtained by multiplying the molality of each ion by its valence squared.
