Question 4.14: Calculating the Quantity of Substance in a Titrated Solution...

Calculating the Quantity of Substance in a Titrated Solution A flask contains a solution with an unknown amount of HCl. This solution is titrated with 0.207 M NaOH. It takes 4.47 mL NaOH to complete the reaction. What is the mass of the HCl?

PROBLEM STRATEGY

You convert the volume of NaOH (4.47  ×  10^{-3} L NaOH solution) to moles NaOH (from the molarity of NaOH). Then you convert moles NaOH to moles HCl (from the chemical equation). Finally, you convert moles HCl to grams HCl.
