**Equilibrium Constant Calculation**

In this exercise, students are asked to determine the partial pressure of \( \text{NH}_3(g) \) using the equilibrium constant for the given reaction at a specific temperature.

**Given Reaction and Data:**

The equilibrium constant, \( K_p \), for the following reaction is \( 1.04 \times 10^{-2} \) at 545 K.

\[
\text{NH}_4\text{Cl}(s) \rightleftharpoons \text{NH}_3(g) + \text{HCl}(g)
\]

**Problem Statement:**

- An equilibrium mixture of the three compounds in a 0.51 L container at 545 K contains:
  - 2.92 mol of \( \text{NH}_4\text{Cl}(s) \) 
  - 0.278 mol of \( \text{NH}_3(g) \)

- Calculate the partial pressure of \( \text{NH}_3(g) \) in the container. Enter your answer in the blank provided.

**Solution Steps:**

To find the partial pressure of \( \text{NH}_3(g) \), use the ideal gas law and the definition of the equilibrium constant.

1. Use the ideal gas law to calculate the pressure of \( \text{NH}_3(g) \).
2. Use the equilibrium expression for the reaction:
   \[
   K_p = \frac{P_{\text{NH}_3} \cdot P_{\text{HCl}}}{1}
   \]
   Since \( K_p \) and the amount of \( \text{NH}_3 \) are known, you can calculate the partial pressure of \( \text{NH}_3 \).

Ensure appropriate use of units and conversion factors to solve for the pressures accurately.
