What is the total number of electrons in of in units of ? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
What is the total number of electrons in $1.6\text{ g}$ of $CH_4$ in units of $N_A$?
Answer: 1
💡 Solution & Explanation
$\text{moles } CH_4 = 1.6 / 16 = 0.1\text{ mol}$. <br>Electrons per molecule $= 6(C) + 4(H) = 10$. <br>Total electrons $= 0.1 \times 10 \times N_A = 1 N_A$.
