Which of the following is incorrect

Question

Answer 1

(c) Its degree of dissociation is 10^-8.

The molal concentration (m) is given by the formula m = 1000 / molar mass (m).

So, the molal concentration is m = \(\frac {1000}{m}\) = \(\frac {1000}{20}\) = 50m

So, the only incorrect information regarding heavy water at 40^∘C is that its degree of dissociation is 10⁻⁸.
