Total number of neutrons in 4.4 g of is [1] — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Moles of $CO_2 = 4.4 / 44 = 0.1$. <br>Neutrons in one molecule of $^{12}C^{16}O_2$: <br>C: $12 - 6 = 6$ neutrons. <br>O: $16 - 8 = 8$ neutrons per atom. <br>Total neutrons per molecule $= 6 + 2(8) = 22$. <br>Total neutrons $= \text{moles} \times N_A \times 22 = 0.1 \times 22 \times N_A = 2.2 N_A$.
