What is Molality?
Molality is nothing but molal concentration and is a measure of the concentration of solute in a solution with regards of substance in a specified amount of mass of the solvent. The changes in the definition of molality are based on a particular volume of given solution.
Units of Molality
The Sl unit for molality is moles per kilogram.
Molality Calculator helps to control the amount of solute that dissolved in a given quantity of solvent or solution.
Methods for Molality Calculator
Basically, you need to read the problem carefully and find out the values given for the moles of the solute and weight of the solvent.
Use the molality formula and substitute the given values in order to get the molality value.
Molality (M)= (Number of moles of solute)/(Weight of solvent in kg )
Stpe3: Check whether the molality values are in a fixed unit.
Problems on Molality Calculator
Concentrated HCl is of 37% by weight; calculate the molality of the solution.
Take the data of 100g solution contains 37g HCl.
Hence weight of solvent= (100-37) =63g
Molality=W/MX1000/(Weight of solvent)
When it comes to step 3 molality is stated as 16.09 mol/kg
The molality of the given concentrated HCL solution is of 16.09 mol/kg
