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 $\frac{1}{10}$ of the mass of one carbon$-12$ atom.
It is equal to $\frac{1}{\text{NA}}$
$\frac{1}{6.022\times10^{23}}$
$= 1.66 \times 10^{-24} \mathrm{~g} $
