We’re being asked to calculate the mass of KHC8H4O4 required to react with 15 mL of 0.16 M NaOH solution.

For this problem, we need to do the following steps:

Step 1: Write and balance a chemical equation for the given reaction.

Step 2: Determine the mass of KHC8H4O4 needed.

Step 1: Since KHC8H4O4 and NaOH are ionic compounds, they form ions when dissociating in water.

The dissociation of the two compounds is as follows:

For KHC8H4O4: Potassium is from Group 1 so it has a charge of +1. This means HC8H4O4 has a charge of –1:

KHC8H4O4 (aq)  K+(aq) + HC8H4O4(aq)

For NaOH: Sodium is from Group 1 so it has a charge of +1. The hydroxide ion has a charge of –1:

NaOH(aq)  Na+(aq) + OH(aq)
