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
$8 g \mathrm{H}_2=4 \mathrm{moles}$
$8 g \mathrm{H}_2=4 \mathrm{moles}$
$64 g$ $SO_2=1$ mole
$44 \mathrm{g} \mathrm{CO}_2=1 \mathrm{mole}$
$48 \mathrm{g} O_2=48 / 32=1.5 \mathrm{mole}$
