Question: Currently, the atomic mass unit (amu) is based on being exactly one-twelfth the mass of a carbon-12 atom and is equal to 1.66 1027

Currently, the atomic mass unit (amu) is based on being exactly one-twelfth the mass of a carbon-12 atom and is equal to 1.66 × 10–27 kg.
a. If the amu were based on sodium-23 with a mass equal to exactly 1/23 of the mass of a sodium-23 atom, would the mass of the amu be different?
b. If the new mass of the amu based on sodium-23 is 1.67 × 10–27 kg, how would the mass of a hydrogen atom, in amu, compare with the current mass of a hydrogen atom in amu?
