In of gas, the total number of electrons is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Moles of } H_2 = 1 / 2 = 0.5 \text{ mol}$. <br>$\text{Molecules} = 0.5 N_A$. <br>Each $H_2$ molecule has 2 electrons. <br>$\text{Total electrons} = 0.5 N_A \times 2 = N_A$.
