MCQ
Which of the following represents $180\, g$ of water correctly ?
- A$5\, moles$ of water
- B$1\, mole$ of water
- C$6.023 \times 10^{23}$ molecules of water
- ✓$6.023 \times 10^{24}$ molecules of water
✓
Answer
Correct option: D.
$6.023 \times 10^{24}$ molecules of water
d
$n=\frac{180}{18}=10$
$n=\frac{180}{18}=10$
no. of molecule $=10 \times 6.02 \times 10^{23}$
$=6.02 \times 10^{24} $
