Taking into account the definition of molarity, the molarity of the solution is 0.408 [tex]\frac{moles}{liter}[/tex]
Molar concentration or molarity is a measure of the concentration of a solute in a solution that is defined as the number of moles of solute that are dissolved in a certain volume.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:
[tex]molarity=\frac{number of moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
In this case, being the molar mass of sulfuric acid 98 g/molar, that is, the mass present in one mole of the compound, you know:
- number of moles of solute= [tex]20 gramsx\frac{1 mole}{98 grams}[/tex]= 0.204 moles
- volume= 500 mL= 0.500 L (being 1000 mL=1 L)
Replacing in the definition of molarity:
[tex]molarity=\frac{0.204 moles}{0.500 L}[/tex]
Solving:
molarity= 0.408 [tex]\frac{moles}{liter}[/tex]
Finally, the molarity of the solution is 0.408 [tex]\frac{moles}{liter}[/tex]
