**Question:**
Calculate the pH of a 0.1 M solution of acetic acid (CH3COOH) given that the dissociation constant (Ka) of acetic acid is ( 1.8 times 10^{-5} ).
**Hint:**
Use the equation for the dissociation of acetic acid and the expression for calculating pH from the concentration of hydrogen ions.
