Question

$1amu$ is equal to $1.66\times {10}^{-24}$ g.

• A. True
• B. False

Answer 1

The correct option is A True

$1amu={\frac{1}{12}}^{th}$ mass of one $C-12$ atom

$N_o$(Avogadro number) = $6.023\times {10}^{23}$

Mass of $6.023\times {10}^{23}$atoms of carbon = $12g$

Mass of $1$ atom of ${}_6^{12}C=\frac{12g}{6.023\times {10}^{23}}$

$\therefore 1amu=\frac{1}{12}\times \frac{12g}{6.023\times {10}^{23}}=1.66\times {10}^{-24}g$
