Question

what is difference between molarity and molality ?​

Answer 1

Answer:

Molarity is number of moles in volume of solution

Molality is number of moles in weight of solution

Answer 2

Answer:

Molarity:- it is defined as the number of moles of the solute dissolved in 1 liter of the solution.

molarity=w×1000÷mm×v in ml.

Molality:-when molecular mass of solute is dissolved in 1 kg of solvent then the solution is known as molal solution. molality is defined as the number of moles of solute present in 1 kg of solvent.

molality=no of moles of solute/mass of solvent in kg..
