### Stoichiometry Problem: Calculating the Mass of NO

#### Problem Statement:
What is the mass in grams of NO that can be formed from 7.26 moles of NO₂ in the reaction below?

\[ 3 \text{NO}_2 (g) + \text{H}_2\text{O} (g) \rightarrow 2 \text{HNO}_3 (g) + \text{NO} (g) \]

#### Introduction:
This problem involves the stoichiometric calculation of the mass of nitrogen monoxide (NO) produced from a given amount of nitrogen dioxide (NO₂). The balanced chemical equation provides the mole ratio necessary for this calculation.

#### Procedure:
1. **Identify the Mole Ratio**: From the balanced reaction, 3 moles of NO₂ produce 1 mole of NO.

2. **Calculate Moles of NO**: 
   Using the given moles of NO₂:
   \[
   \frac{7.26 \text{ moles NO}_2}{3 \text{ moles NO}_2} = 2.42 \text{ moles NO}
   \]

3. **Calculate Mass of NO**:
   The molar mass of NO is approximately 30 g/mol. So, the mass of NO formed is:
   \[
   2.42 \text{ moles NO} \times 30 \text{ g/mol} = 72.6 \text{ g}
   \]

### Conclusion:
Given 7.26 moles of NO₂, 72.6 grams of NO can be produced under the conditions described by the balanced chemical equation.

#### Interface Details:
- **Calculator Interface**: The problem appears on an educational platform with an integrated calculator interface for inputting numerical data and performing calculations.
- **Graphical Elements**: There are no graphical elements or diagrams associated with this problem. The focus is on understanding and applying the stoichiometric relationships described in the equation.
