Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.

Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:

$Molarity=\frac{number of moles of solute}{volume}$

Molarity is expressed in units $\frac{moles}{liter}$ .

In this case:

number of moles of solute= 2.1 moles
volume= 7.3 liters

Replacing:

$Molarity=\frac{2.1 moles}{7.3 liters}$

Molarity= 0.29 $\frac{moles}{liter}$

The molarity of the solution is 0.29 $\frac{moles}{liter}$
