A chemist must dilute 10.3mL of 4.00M aqueous sodium chloride NaCl solution until the concentration falls to 3.00M . He'll do this by adding distilled water to the solution until it reaches a certain final volume.

Required:
Calculate this final volume, in liters.

Answer:

The final volume of the solution is 0.01373 Liters.

Explanation:

Concentration of the NaCl solution = [tex]M_1=4.00 M[/tex]

Volume of the NaCl solution = [tex]V_1=10.3 mL[/tex]

Concentration of the NaCl solution after dilution = [tex]M_2=3.00 M[/tex]

Volume of the NaCl solution after dilution = [tex]V_2=?[/tex]

[tex]M_1V_1=M_2V_2[/tex]  (dilution)

[tex]V_2=\frac{M_1V_1}{M_2}=\frac{4.00M\times 10.3 mL}{3.00 M}=13.73 mL[/tex]

1 mL = 0.001 L

13.73 mL = 13.73 × 0.001 L = 0.01373 L

The final volume of the solution is 0.01373 Liters.
