Complete the following $mo\frac{l}{L}$ redox titration lab report.

Problem

What is the concentration of a sodium nitrate solution?

Experimental Design

A standard solution of potassium iodide was prepared. $10\mathrm{.}0mL$ samples of the sodium nitrate solution were titrated with the acidified potassium iodide.

Evidence

Mass of solid potassium iodide dissolved to make $100\mathrm{.}0mL$ of solution $=2\mathrm{.}33g$

Concentration of $KI(aq)=.$

Volume of Acidified $KI($aq$)$ reacting with $10\mathrm{.}0mL$ of $NaN{O}_3($aq$)$
