Question

how does the molality of a solution diffrent from its molarity

Answer 1

  Molarity is defined as the number of moles of solute per liter of solution. This means that if you have a 1 M solution of some compound, evaporating one liter will cause one mole of the solute to precipitate. 

Molality is defined as the number of moles of solute per kilogram of solvent. To make a 1 m solution, you'd take one mole of a substance and add it to 1 L of solvent. As a result, the final volume of a 1 m solution will be somewhat more than 1 L. 

Answer 2

⭐Molality is then the number of moles of solute per kilogram of the SOLVENT, NOT solution! ...
⭐That is because morality does not depend on temperature, (Neither number of moles of solute nor mass of solvent will be affected by changes of temperature.) while MOLARITY changes as temperature changes....
