(A) Concentrated nitric acid is typically obtained by the distillation of a mixture of $NaNO_3$ or $KNO_3$ and concentrated $H_2SO_4$. However,the maximum concentration of aqueous $HNO_3$ that can be achieved by distillation is approximately $68 \%$ by mass. Further concentration to $98 \%$ can be achieved by dehydration with concentrated $H_2SO_4$.

What is the maximum concentration of aqueous $HNO_3$ that can be obtained by distillation with concentrated $H_2SO_4$ in terms of percentage by mass (in $\%$)?
