MCQ
The value of $1$ amu is equal to :
- A$1.66 \times 10^{-8} \mathrm{~g}$
- B$1.66 \times 10^{-4} \mathrm{~g}$
- C$1.66 \times 10^{-16} \mathrm{~g}$
- ✓$1.66 \times 10^{-24} \mathrm{~g}$
✓
Answer
Correct option: D.
$1.66 \times 10^{-24} \mathrm{~g}$
One an amu is $\frac{1}{2}$ of the mass of one carbon $-12$ atom.
It is equal to $\frac{1}{\text{N}_\text{A}}$
$\frac{1}{6.022\times10^{23}}=1.66\times10^{-24}\text{g}$
It is equal to $\frac{1}{\text{N}_\text{A}}$
$\frac{1}{6.022\times10^{23}}=1.66\times10^{-24}\text{g}$
