### Chemical Equilibrium Problem

#### Given Reaction:
\[ \text{H}_2\text{O}(g) + \text{Cl}_2\text{O}(g) \rightleftharpoons 2\text{HOCl}(g) \]

The equilibrium constant (\(K\)) for this reaction at 298 K is given as:
\[ K = 0.0900 \]

#### Problem Statement:
A sealed 2.00 L reaction vessel is initially charged with 3.00 moles of \(\text{H}_2\text{O}\) gas and 4.00 moles of \(\text{Cl}_2\text{O}\) gas. Calculate the equilibrium concentrations of the components in the reaction. Specifically, determine the equilibrium concentration of \(\text{H}_2\text{O}\).

#### Equilibrium Concentration Calculation:

We need to find the equilibrium concentration of \(\text{H}_2\text{O} (g)\), represented as \([\text{H}_2\text{O}] = ? \text{ M} \).

#### Input Box:
There is an input field labeled [ \(\text{H}_2\text{O}\), \(\text{M}\)] where the equilibrium concentration value of \(\text{H}_2\text{O}\) should be entered.

#### Instructions:
1. Using the initial moles and the volume of the vessel, determine the initial concentrations of the reactants.
2. Apply the ICE (Initial, Change, Equilibrium) table method to find the changes in concentrations as the system reaches equilibrium.
3. Use the given equilibrium constant (\(K\)) to set up the equilibrium expression.
4. Solve for the unknown concentrations, ensuring you account for the stoichiometry of the balanced equation.
5. Enter the equilibrium concentration of \(\text{H}_2\text{O}\) in the provided box.

Feel free to refer to your course materials or textbooks for detailed steps on utilizing the ICE table method and solving equilibrium problems.
