$CO$

Vedclass · Answer

(A) According to Avogadro's Law,equal volumes of all gases at the same temperature and pressure contain an equal number of molecules.Since the volume of $N_2$ and gas $x$ are equal ($10 \ dm^3$ each) at the same temperature and pressure,they must contain the same number of molecules.However,the question implies identifying a gas that is chemically equivalent or has the same molar mass as $N_2$ $(28 \ g/mol)$.$N_2$ molar mass $= 2 	imes 14 = 28 \ g/mol$.$CO$ molar mass $= 12 + 16 = 28 \ g/mol$.Thus,$CO$ is the gas $x$.

At the same temperature,$10 \ dm^3$ of $N_2$ gas and $10 \ dm^3$ of gas $x$ contain the same number of molecules. What is the gas $x$?
