Taking into account the definition of molarity, the concentration of CH₃OH in the solution is 3.12 .
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 is expressed in units .
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:
Solving:
<u><em>Molarity= 3.12 </em></u>
Finally, the concentration of CH₃OH in the solution is 3.12 .
