MCQ
The number of water molecules is maximum in
- A$1.8\ gram$ of water
- B$18\ gram$ of water
- ✓$18\ moles$ of water
- D$18$ molecules of water.
✓
Answer
Correct option: C.
$18\ moles$ of water
c
No of moles of water in $1.8 \mathrm{g}=0.1$ moles
No of moles of water in $1.8 \mathrm{g}=0.1$ moles
$\ln 18 \;\mathrm{g}=1 \mathrm{moles}$
$1\; mole$ contain $6.022 \times 10^{23}$ molecules of water
so $18\; moles$ contain maximum number of molecules
