How to Calculate Molality
So when 1 gm mole
solute dissolved in 1 Kg solvent it’s called 1 molar or 1 M
solution.
Symbol for Molarity is
“m”
Molality = (weight of
solute in gram) / (Molecular weight of solute × weight of solvent in Kg)
Means final weight of
solution may be more than 1 Kg.
No matter of volume
involve in this case.
Change in temperature
will change the volume, so
Molarity will change with temperature but
Molality will remain constant with change in temperature, because it doesn’t
have relation with volume.
