Vedclass · Answer

(D) $1$. For $CO_2$: $n = \frac{11.2 \, L}{22.4 \, L/mol} = 0.5 \, mol$. Number of atoms = $0.5 	imes 3 	imes N_A = 1.5 N_A$.$2$. For $H_2$: $n = \frac{2 \, g}{2 \, g/mol} = 1 \, mol$. Number of atoms = $1 	imes 2 	imes N_A = 2 N_A$.$3$. For $C$: $2 \, g$-atom means $2 \, moles$ of $C$ atoms. Number of atoms = $2 N_A$.$4$. For $SO_2$: $3 \, g$-molecule means $3 \, moles$ of $SO_2$ molecules. Number of atoms = $3 	imes 3 	imes N_A = 9 N_A$.Comparing all,$9 N_A$ is the highest.
