Answer:
0.3 mol/L is the concentration of the diluted solution in the 50 mL volumetric flask.
Explanation:
We have 100 mL of solution with a concentration of 1.50 mol/L.
Molarity of the solution before dilution = [tex]M_1=1.50 mol/L[/tex]
Volume 1.50 mol/L solution added in 50 mL volumetric flask = [tex]V_1=10 mL[/tex]
Molarity of the solution after dilution = [tex]M_2=?[/tex]
Volume of solution after dilution = [tex]V_2=50 mL[/tex]
[tex]M_1V_1=M_2V_2[/tex] (dilution)
[tex]M_2=\frac{M_1V_1}{V_2}=\frac{1.50 mol/L\times 10 mL}{50 mL}[/tex]
[tex]M_2=0.3 mol/L[/tex]
0.3 mol/L is the concentration of the diluted solution in the 50 mL volumetric flask.
