**Problem 15.35 - Enhanced - with Feedback**

**Introduction:**
A mixture of 0.10 mol of NO, 0.050 mol of H₂, and 0.10 mol of H₂O is placed in a 1.0-L vessel at 300 K. The following equilibrium is established:

\[ 2\text{NO}(g) + 2\text{H}_2(g) \rightleftharpoons \text{N}_2(g) + 2\text{H}_2\text{O}(g) \]

At equilibrium, \([\text{NO}] = 0.062 \, \text{M}\).

**Problem:**
Calculate the equilibrium concentration of \(\text{H}_2\text{O}\).

- **Instructions:** Express the molarity to three decimal places.
- **Input Interface:** A text box where the concentration can be entered. Options include undo, redo, reset, keyboard shortcuts, and help.
