MCQ
Which has the maximum number of molecules among the following?
  • A
    $44\; g\ CO_2$
  • B
    $48\; g\ O_3$
  • $8\; g\  H_2$
  • D
    $64\;  g\  SO_2$

Answer

Correct option: C.
$8\; g\  H_2$
c
$8 g \mathrm{H}_2=4 \mathrm{moles}$

$64 g$ $SO_2=1$ mole

$44 \mathrm{g} \mathrm{CO}_2=1 \mathrm{mole}$

$48 \mathrm{g} O_2=48 / 32=1.5 \mathrm{mole}$
