Question
**Question:**
How many moles of ammonia would be required to react exactly with 0.734 moles of copper(II) oxide in the following chemical reaction?

\[ 2 \text{NH}_3(g) + 3 \text{CuO}(s) \rightarrow 3 \text{Cu}(s) + \text{N}_2(g) + 3 \text{H}_2\text{O}(g) \]

**Calculator Interface:**

- A numerical keypad is displayed with numbers 1 to 9, a '0', and options for decimal point and plus/minus sign.
- There are buttons for clearing the input (C) and deleting the last entry (backspace symbol).
- The display area is labeled "mol" to indicate the unit of measurement for the input.

**Note:**
To solve this problem, use stoichiometry based on the balanced chemical equation: The ratio of NH₃ to CuO is 2:3. Calculate using this ratio:
\[ \text{Moles of NH}_3 = \left(\frac{2}{3}\right) \times 0.734 \, \text{mol of CuO} \]

This calculation will provide the moles of ammonia needed for the reaction.
