**Determining the Volume of Base Needed to Titrate a Given Mass**A chemistry student weighs out 0.300 g of citric acid (H₃C₆H₅O₇), a triprotic acid, into a 250 mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.2000 M NaOH solution.Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Round your answer to 3 significant digits.**Response:**7.81 mLThis problem involves understanding the titration process, specifically using sodium hydroxide (NaOH) to neutralize citric acid (H₃C₆H₅O₇). The task requires calculating the necessary volume of a 0.2000 M NaOH solution to fully neutralize a given amount of citric acid.- **No graphs or diagrams** are present in this image.Additional features:- "Try Again" button: Indicates an opportunity to retry the calculation.- "Explanation" and "Recheck" buttons: Likely provide further details or allow verification of the calculation process.
