Concentrated nitric acid used in laboratory work is nitric acid by mass in aqueous solution. What should be the molarity of such a sample of the acid if the density of the solution is ?
Solution 4: $68 \%$ nitric acid by mass means that $68 \mathrm{~g}$ mass of nitric acid is dissolved in $100 \mathrm{~g}$ mass the solution. Molar mass of $\mathrm{HNO}_{3}=63 \mathrm{~g}...
Define the following terms:
(i) Mole fraction
(ii) Molality
