Question

The maximum volume at S.T.P. is occupied by:

• A. $12.8 \, g$ of $SO _{2}$
• B. $6.02 \times 10^{22}$ molecules of $CH _{4}$
• C. $0.5\, mL$ of $NO _{2}$
• D. $1 \, g$ molecule of $CO _{2}$

Answer 1

Answer: (D)

$12.8\, g$ of $SO _{2}=4.48\, L$

$6.02 \times 10^{22}$ molecules of $CH _{4}=2.24 \,L$

$0.5 \, mol$ of $NO _{2}=11.2 L$

$1\, g$ molecule of $CO _{2}=22.4 L$
