The `pK_(a)` of `CH_(3)COOH` and `pK_(a)` of `nH_(4)OH` is `4.76` and `4.75`, respectively. Calculate the hydrolysis constant of ammonium acetate `(CH_(3)COONH_(4))` at `298K` and also the drgree of hydrolysis and `pH` of its (a) `0.01M` and (b) `0.04M` solutions.

Explanation

To solve the problem step by step, we will calculate the hydrolysis constant of ammonium acetate, the degree of hydrolysis, and the pH for both 0.01 M and 0.04 M solutions.

### Step 1: Calculate the Hydrolysis Constant (K_h)

The hydrolysis constant \( K_h \) for the salt of a weak acid and a weak base can be calculated using the formula:

\[
K_h = \frac{K_w}{K_a \cdot K_b}
