Question

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:

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

    Using formula:

    V_1=\frac{V_2 C_2}{C_1}\\\\

         =\frac{1000 \ mL \times 13.750 \ \frac{g}{L}}{68.2 \ \frac{g}{L}}\\\\= 201.61 \ mL
