If 2.1 moles of NaCl is dissolved in a solution with a total volume of 7.3 liters, what is the molarity of the solution? Round to two decimals.

The molarity of the solution is 0.29

Explanation:

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 is expressed in units .

In this case:

number of moles of solute= 2.1 molesvolume= 7.3 liters

Replacing:

Molarity= 0.29

The molarity of the solution is 0.29
