Calculating pH of Weak Acid Solution

In a laboratory experiment, a chemist prepares a solution by dissolving compound X in water, where compound X is a weak acid that partially dissociates in solution. The dissociation constant (Ka) for this acid is known to be 5.0 x 10^-5. If the chemist dilutes the solution to a concentration of 0.1 M and measures the pH, what would be the expected pH value of the solution?

Consider the equilibrium established during the dissociation of the weak acid: HA ↔ H⁺ + A^-. Use the provided Ka value to calculate the pH.
