Which of the following gaseous mixtures have the same density at STP? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Density} \propto \text{Molar mass}$ at STP. $N_2$ and $CO$ both have $MW = 28$. $CO_2$ and $N_2O$ both have $MW = 44$. Therefore, their densities are identical.
