Question Stem
At 298 K, the limiting molar conductivity of a weak monobasic acid is $$4 \times 10^2 S cm^2 mol^{-1}$$. At 298 K, for an aqueous solution of the acid the degree of dissociation is $$\alpha$$ and the molar conductivity is $$๐ฒ \times 10^2 S cm^2 mol^{-1}$$. At 298 K, upon 20 times dilution with water, the molar conductivity of the solution becomes $$3๐ฒ \times 10^2 S cm^2 mol^{-1}$$.

Question 45

The value of $$\alpha$$ is ___.


Correct Answer: 0.20 - 0.22
