Question

what are the units of concentration​

Answer 1

Answer:

Quantitative units of concentration include molarity, molality, mass percentage, parts per thousand, parts per million, and parts per billion...

Answer 2

$\huge\red{\boxed{\bold{Answer}}}$

• The concentrations of solutions may be expressed in the following common set of units.

$\large\underline\mathrm\red{Molarity:-}$

The molarity of a solution is the number of moles of solute present in one litre of the solution. It is expressed by 'M'.

$\large\underline\mathrm\red{Demal \: unit :-}$

The concentrations are also expressed in Demal units. One Demal unit represents one mole of solute present in one litre of the solution at 0° c. It is expressed by 'D'

$\large\underline\mathrm\red{Molality:-}$

The molality is defined as the number of moles of the solute present in 1000 g of the solvent. It is symbolised by 'm'.

$\large\underline\mathrm\red{Normality:-}$

The normality is the number of equivalents of solute present in one litre of the solution. It is expressed by 'N'.

$\large\underline\mathrm\red{Formality:-}$

The formality is the number of gram formula weight of the solute per litre of the solution. It is expressed by 'F'.
