Question

Differentiate be molarity and molality​

Answer 1

Answer:

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

Answer 2

Molality (m) and molarity (M) both express the concentration of a chemical solution.

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 1 kg of solvent.

2. It depends on mass.

3. It depends on mass which is independent of temperature.

Conversion:

To convert Molality value into Molarity value, we have to use the following formula:-

m = 1000× M

1000×(d-M) × Mb

or, M = d

(m×Mb) + 1

where, M: molarity, m: molality, d: density, Mb: Molecular mass.
