Question
**Determining the Volume of Base Needed to Titrate a Given Mass**

A chemistry student weighs out 0.217 g of lactic acid (HC₃H₅O₃) into a 250. mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.0900 M NaOH solution.

Calculate the volume of NaOH solution the student will need to add to reach the equivalence point. Be sure your answer has the correct number of significant digits.

**[Input Box] mL**

**Options:**
- Enter the calculated volume.
- Reset or clear the input.

Note: Ensure your calculation considers stoichiometry and molarity to determine the correct volume required for neutralization.

**Buttons:**
- Explanation
- Check

This problem focuses on teaching students how to calculate the volume of a titrant needed to neutralize a given amount of an acid, using the concepts of molarity and stoichiometry.
