Explanation / Answer

The answer here is correct till the last step.

They have calculated the ratio for [HCO3-]/[H2CO3] correctly.

But your question asks the ratio of acid to the salt, i.e.

[H2CO3]/[HCO3-], so we just have to inverse the answer.

We have,

[HCO3-]/[H2CO3] = 6.16

So, [H2CO3]/[HCO3-] = 1/6.16 = 0.162 Answer.
