### Equilibrium Calculation Example

**Problem Statement:**
Calculate the number of moles of HI that are at equilibrium with 1.25 mol of H₂ and 1.25 mol of I₂ in a 5.00-L flask at 448 °C.

The balanced chemical equation for the reaction is:

\[ \text{H}_2 + \text{I}_2 \rightleftharpoons 2\text{HI} \]

The equilibrium constant (\( K_c \)) for this reaction at 448 °C is given as:

\[ K_c = 50.2 \text{ at 448 °C} \]

In this problem, we need to find the equilibrium concentration of HI in the flask.
