A stock solution has a concentration of 68.2 g/L. A 13.750 g/L solution is required. If you use a 1000.0 mL volumetric flask for the dilution, what volume (in ml) needs to be taken from the stock solution? Give your answer to three significant figures.

Answer:

The answer is "".

Explanation:

[tex]C_1=68.2 \ \frac{g}{L}\\\\V_2=1000.0 \ mL \\\\C_2=13.750 \ \frac{g}{L}\\\\V_1=?[/tex]

Using formula:

[tex]V_1=\frac{V_2 C_2}{C_1}\\\\[/tex]

     [tex]=\frac{1000 \ mL \times 13.750 \ \frac{g}{L}}{68.2 \ \frac{g}{L}}\\\\= 201.61 \ mL[/tex]
