Calculate the molarity of solution of "sodium sulfate" that contains 5.2 grams sodiums sulfate diluted to 500mL
wlad13 [49]

Taking into account the definition of molarity, the molarity of solution of sodium sulfate is 0.0732 \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 solution of sodium sulfate.</h3>

In this case, you have:

  • number of moles of sodium sulfate= 5.2 grams\frac{1 mole}{142 grams} = 0.0366 moles (being 142 g/mole the molar mass of sodiums sulfate)
  • volume= 500 mL= 0.5 L (being 1000 mL= 1 L)

Replacing in the definition of molarity:

Molarity=\frac{0.0366 moles}{0.5 L}

Solving:

Molarity= 0.0732 \frac{moles}{liter}

Finally, the molarity of solution of sodium sulfate is 0.0732 \frac{moles}{liter}.
