Total number of neutrons in 4.4 g of is — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
Total number of neutrons in 4.4 g of $CO_2$ is
Answer: B
💡 Solution & Explanation
$\text{Moles of } CO_2 = 4.4/44 = 0.1$. Neutrons per molecule $= 6(C) + 2 \times 8(O) = 22$. $\text{Total neutrons} = 0.1 \times 22 \times N_A = 2.2 N_A$. [2]
