Taking into account the definition of molarity, the concentration of CH₃OH in the solution is 3.12
.
<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}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7Bnumber%20of%20moles%7D%7Bvolume%7D)
Molarity is expressed in units
.
<h3>Concentration of CH₃OH</h3>
In this case, you know:
- number of moles= 50 g×
= 1.56 moles, being 32.04
the molar mass of CH₃OH - volume= 500 mL= 0.5 L (being 1000 mL= 1 L)
Replacing in the definition of molarity:
![Molarity=\frac{1.56 moles}{0.500 L}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7B1.56%20moles%7D%7B0.500%20L%7D)
Solving:
<u><em>Molarity= 3.12 </em></u>![\frac{moles}{liters}](https://tex.z-dn.net/?f=%5Cfrac%7Bmoles%7D%7Bliters%7D)
Finally, the concentration of CH₃OH in the solution is 3.12
