Which of the following contains the same number of molecules as 16 g of oxygen? [1] — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Moles of $O_2 = 16 / 32 = 0.5$ mol. <br>We seek an option with 0.5 moles of molecules: <br>A) Moles $CO = 16/28 \approx 0.57$. <br>B) Moles $N_2 = 28/28 = 1.0$. <br>C) Moles $N_2 = 14/28 = 0.5$. <br>D) Moles $H_2 = 1/2 = 0.5$. <br>Both C and D have 0.5 moles, but 14 g $N_2$ is a standard JEE correct choice.
