Molarity is the molar concentration of the solute dissolved in a volume of a solution. The molarity of the solution prepared by dissolving barium chloride will be 0.085 M.
Molarity is the ratio of the moles of the solute to that of the volume of the solution in Liters. It can be given as,
[tex]\rm Molarity = \dfrac{moles}{Volume}[/tex]
Here, moles of the barium chloride can be given by the mass and the molar mass and volume is given as 0.450 L.
Substituting values in the equation:
[tex]\begin{aligned}\rm Molarity &= \rm \dfrac{mass}{Molar \;mass\times Volume}\\\\&= \dfrac{8}{208.23\times 0.450}\\\\&= 0.085\;\rm M\end{aligned}[/tex]
Therefore, 0.085 M barium chloride is the molar concentration.
