Answer

10.00 mL Explanation 1. Use the dilution formula The formula for dilution is **\( C_1V_1 = C_2V_2 \)**, where \( C_1 \) and \( V_1 \) are the concentration and volume of the stock solution, and \( C_2 \) and \( V_2 \) are the concentration and volume of the diluted solution. 2. Substitute known values Given \( C_1 = 0.16 \, \text{M} \), \( C_2 = 0.016 \, \text{M} \), and \( V_2 = 100.00 \, \text{mL} \). Substitute these into the formula: \[ 0.16 \times V_1 = 0.016 \times 100.00 \] 3. Solve for \( V_1 \) Rearrange to find \( V_1 \): \[ V_1 = \frac{0.016 \times 100.00}{0.16} \] 4. Calculate \( V_1 \) Perform the calculation: \[ V_1 = \frac{1.6}{0.16} = 10.00 \, \text{mL} \]
