Question

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

• A. True
• B. False

Answer 1

The correct option is A True

Atomic Mass Unit (AMU): The atomic mass unit (AMU) is equal to one-twelfth $\left(\frac{1}{12}\right)th$ the mass of one atom of the carbon-12 isotope.

1 AMU = $\left(\frac{1}{12}\right)$× mass of one C-12 atom

The mass of one nucleon in a C-12 atom. = 1.66 × 10^-24 gm or 1.66 × 10^-27 kg
