MCQ
Which is heaviest
- A$25\,gm$ of mercury
- B$2 \,moles$ of water
- ✓$2\,moles$ of carbon dioxide
- D$4\,gm$ atoms of oxygen
✓
Answer
Correct option: C.
$2\,moles$ of carbon dioxide
c
Mass of $1\, mole$ of carbon dioxide $=44 \,g$
Mass of $1\, mole$ of carbon dioxide $=44 \,g$
So, the mass of $2 \,moles$ of carbon dioxide $=88\, g$
Hence, $2\, moles$ of carbon dioxide is heaviest and the correct option is $C$.
