Question

define molality. write the formula and unit of molality. ​

Answer 1

Answer:

Molality is a measure of number of moles of solute present in 1 kg of solvent. This contrasts with the definition of molarity which is based on a specified volume of solution. A commonly used unit for molality in chemistry is mol/kg. A solution of concentration 1 mol/kg is also sometimes denoted as 1 molal.

Formula

Molality=m=Mole of solute/Kg of solvent

Unit=mol/Kg or mol kg-¹

Answer 2

Answer:

Molality (m) is defined as the number of moles of solute per kilogram of solvent. The formula for molality is given as; Molality (m) = moles of solute / kilograms of solvent. Students have to remember that molality is used to measure the moles in relation to the mass of the solvent and not the mass of the solution.
