Question
**Calculating Equilibrium Molarity of \( \text{H}_2\text{O} \) in a Chemical Reaction**

---

**Problem Statement:**
Suppose a 500. mL flask is filled with 1.9 mol of CO, 0.60 mol of \( \text{H}_2\text{O} \), and 1.7 mol of \( \text{H}_2 \). The following reaction becomes possible:

\[
\text{CO} (g) + \text{H}_2\text{O} (g) \rightleftharpoons \text{CO}_2 (g) + \text{H}_2 (g)
\]

The equilibrium constant \( K \) for this reaction is 1.81 at the temperature of the flask. 

**Task:**
Calculate the equilibrium molarity of \( \text{H}_2\text{O} \). Round your answer to two decimal places.

---

**Additional Information:**
- This question involves determining the equilibrium concentrations in a chemical equilibrium scenario.
- The molarity \( M \) of a substance is the number of moles divided by the volume (in liters) of the solution.

**Graphical/Diagrammatic Details:**
- There is no specific graph or diagram provided with the problem; however, the equilibrium expression should be set up based on the given initial conditions and equilibrium constant. 

---

**Answer Box:**
Enter the calculated equilibrium molarity of \( \text{H}_2\text{O} \) in the provided box. 

---

\[ M \: \boxed{\: \: \: \: } \]
