Question

Molality of a solution is 0.1m.Elaborate with an example​

Answer 1

Answer:

molality of a solution is defined as the number of moles of solute per kilogram of solvent.

Molality = moles of solute / kilograms of solvent

SI units of molality are: mol/kg

So in your case the molality is 0.1 mol/kg, so 0.1 moles of solute per kilogram of solvent.

Please do not confuse Molality with Molarity. Molarity is something different which takes into consideration the volume of the solution instead of the mass.

Answer 2

Answer:

Molality of a solution is 0.1m means that there is 0.1 moles of solute in 1kg of solvent.

Explanation:

Molality is a measure of the concentration of a solute in a solution in terms of amount of substance in a specified amount of mass of the solvent(in kg). It is also called molal concentration.

Molality = Moles of solute / Mass of solvent in kg

If molality of a solution is 0.1m  then it means that we have 0.1 moles of solute dissolved in 1kg of solvent.

For example,

If we are adding 7.45 grams of KCl (solute) in 1kg of water (solvent) then,

Molecular weight of KCl = 39+35.5=74.5

Number of moles of KCl$=\frac{7.45}{74.5}=0.1$

Molality$=\frac{0.1}{1kg}=0.1$
