Which of the following represent(s) the same mass? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

1 mole $N_2 = 28$ g. 28 g $CO$ is 28 g. <br>"1 g-molecule" $= 1$ mole molecules. <br>"2 g-molecule of N" would imply 2 moles of $N_2$ (56 g). (If it meant g-atom, it would be 28 g). Usually, g-molecule refers to the molecular form.
