Suppose you have a sample of table salt (NaCl) that has a mass of 100.0 grams. If

IgorC [24]

Taking into account the definition of molarity, the concentration of the solution is 0.855 $\frac{moles}{liter}$ .

<h3>Definition of molarity</h3>

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:

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

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

<h3>Molarity of NaCl</h3>

In this case, you have:

number of moles of NaCl= $100 grams\frac{1 mole}{58.45 grams} =$ 1.71 moles (being 58.45 g/mole the molar mass of NaCl)
volume 2 L

Replacing in the definition of molarity:

$Molarity=\frac{1.71 moles}{2 L}$

Solving:

Molarity= 0.855 $\frac{moles}{liter}$

Finally, the concentration of the solution is 0.855 $\frac{moles}{liter}$ .
