Calculate the concentration of hydroxyl ions in a 0.1 M solution of ammonia if the value of `K_b` is `1.76 xx 10^(-5)`

Explanation

To calculate the concentration of hydroxyl ions \([OH^-]\) in a 0.1 M solution of ammonia (\(NH_3\)), we can follow these steps:

### Step 1: Write the equilibrium expression
Ammonia acts as a weak base and dissociates in water according to the following reaction:
\[ NH_3 + H_2O \rightleftharpoons NH_4^+ + OH^- \]
The base dissociation constant \(K_b\) for this reaction is given by:
...
