298\,\text{K}

, the limiting molar conductivity of a weak monobasic acid is

4\times 10^2\,\text{S cm}^2\,\text{mol}^{-1}

. At

298\,\text{K}

, for an aqueous solution of the acid the degree of dissociation is

\alpha

and the molar conductivity is

y\times 10^2\,\text{S cm}^2\,\text{mol}^{-1}

. At

298\,\text{K}

, upon 20 times dilution with water, the molar conductivity of the solution becomes

3y\times 10^2\,\text{S cm}^2\,\text{mol}^{-1}

. The value of

y

is:
