Verified step by step guidance

Start by understanding the relationship between moles, molarity, and volume. The formula to use is: \( \text{Moles} = \text{Molarity} \times \text{Volume} \).
Rearrange the formula to solve for volume: \( \text{Volume} = \frac{\text{Moles}}{\text{Molarity}} \).
Substitute the given values into the equation: \( \text{Volume} = \frac{0.00168 \text{ moles}}{0.107 \text{ M}} \).
Calculate the volume in liters first, then convert it to milliliters by multiplying by 1000 (since 1 L = 1000 mL).
Verify the units and ensure the final answer is in milliliters, which will help you choose the correct option from the given choices.
