The number of molecules in of a gas at and pressure is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
The number of molecules in $8.96 \text{ L}$ of a gas at $0^{\circ}C$ and $1 \text{ atm}$ pressure is:
Answer: A
💡 Solution & Explanation
$\text{Moles} = \frac{\text{Volume}}{22.4} = \frac{8.96}{22.4} = 0.4 \text{ mol}$. <br>$\text{Number of molecules} = 0.4 \times N_A$.
