The number of electrons in of ion is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Moles of } O_2^{2-} = 1.6 / 32 = 0.05\text{ mol}$. <br>Electrons per ion $= 8 \times 2 + 2 = 18$. <br>Total electrons $= 0.05 \times 18 \times N_A = 0.9 N_A$.
