Taking into account the definition of molarity, the molarity of the solution is 2 [tex]\frac{moles}{liter}[/tex].
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
[tex]Molarity=\frac{number of moles}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
In this case, 26.8 g of ammonium chloride is dissolved in water to make a 0.25 L solution. So you know:
Replacing in the definition of molarity:
[tex]Molarity=\frac{0.50 moles}{0.25 L}[/tex]
Solving:
Molarity= 2 [tex]\frac{moles}{liter}[/tex]
Finally, the molarity of the solution is 2 [tex]\frac{moles}{liter}[/tex].
