Answer: The concentration of barium chloride is [tex]3.0\times 10^1\mu M[/tex]
Explanation:
To calculate the molarity of solution, we use the equation:
[tex]\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in L)}}[/tex]
Let us assume:
Moles of barium chloride = [tex]8.9\mu mol[/tex]
Volume of flask = 300 mL
Putting values in above equation, we get:
[tex]\text{Molarity of solution}=\frac{8.9\mu mol\times 1000}{300mL}=3.0\times 10^1\mu M[/tex]
Hence, the concentration of barium chloride is [tex]3.0\times 10^1\mu M[/tex]
