The pH of a 0.01 M weak acid

\mathrm{HX}\left(\mathrm{K}_a=4 \times 10^{-10}\right)

is found to be 5 . Now the acid solution is diluted with excess of water so that the pH of the solution changes to 6 . The new concentration of the diluted weak acid is given as

x \times 10^{-4} \mathrm{M}

. The value of
