When $\displaystyle 800$ mL of $\displaystyle 0.5$ M nitric acid is heated in a beaker, its volume is reduced to half and $\displaystyle 11.5$ g of nitric acid is evaporated. The molarity of the remaining nitric acid solution is $\displaystyle x \times 10^{-2} \mathrm{M}$. (Nearest Integer)
(Molar mass of nitric acid is $\displaystyle 63 \mathrm{~g} \mathrm{~mol}^{-1}$ )
Official answer
54
