$73$ Use the following equation to calculate the concentration of nitric acid, substituting your average volume of NaOH

in liters into the first term. Record your value in Data Table $1.$

concentration $HN{O}_3=$xLNaOH$\frac{0\mathrm{.}1104(mol)NaOH}{L}\frac{1(mol)HNO}{3}\frac{1}{1(mol)NaOH}\frac{1}{0\mathrm{.}010000(L)HN{O}_3}$

$74$ Use the following equation to calculate the percent error of your calculated nitric acid concentration compared to

the true value $(0\mathrm{.}2099$ M$).$ Record your value in Data Table $1.$

percent error $=\frac{|\text{m}\text{e}\text{a}\text{s}\text{u}\text{r}\text{e}\text{d}\text{v}\text{a}\text{l}\text{u}\text{e}-\text{t}\text{r}\text{u}\text{e}\text{v}\text{a}\text{l}\text{u}\text{e}|}{\text{t}\text{r}\text{u}\text{e}\text{v}\text{a}\text{l}\text{u}\text{e}}100\%$
