Which has maximum number of molecules? [1] — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Calculate moles for each: <br>A) $N_2: 7/28 = 0.25$ mol. <br>B) $H_2: 2/2 = 1.0$ mol. <br>C) $NO_2: 16/46 \approx 0.35$ mol. <br>D) $O_2: 16/32 = 0.5$ mol. <br>$H_2$ has the most moles and thus most molecules. [1]
