Question

What are the differences between molarity and molality?​

Answer 1

Following are the differences :-

differences :-

Molarity

1. The number of moles of solute present

in per liter of solution.

2. It depends on volume.

3. Volume changes with temperature, hence it is temperature dependent. Molality

1. The number of moles of solute present in 1kg of solvent.

2. It depends on volume.

3. Volume changes with temperature, hence it is temperature dependent.

Answer 2

Answer:

${\huge{\sf{\red{\underline{\underline{ Aɳʂɯҽɾ }}}}}}$

Both molarity and molality are measures of a chemical solution’s concentration. The primary difference between the two comes down to mass versus volume.

An important distinction between molality and molarity is the difference between a solution and a solvent.

Molarity is the ratio of the moles of a solute to the total liters of a solution. The solution includes both the solute and the solvent.

Molality, on the other hand, is the ratio of the moles of a solute to the kilograms of a solvent.
