For a mixture of and at STP, which of the following is/are correct? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Both $N_2$ and $CO$ have a molar mass of $28 \text{ g/mol}$. Total mass $= 28+28=56 \text{ g}$. Moles $= 2$, so volume $= 44.8 \text{ L}$. Since molar masses are same, densities at STP are same. Each is diatomic, so total atoms $= 2 \text{ mol} \times 2 = 4 \text{ mol}$.
