What is the mass equivalent to 1 amu?
of C -12 isotope
of O -16 isotope
H - 1 isotope
of the He atom

Atomic Mass Unit -
amu is used to measure mass of individual atoms.
- wherein
mass of one atom of Helium= 4 amu
Today, ‘amu’ has been replaced by ‘µ’ which is known as unified mass.
1 amu = of the mass of C-12 atom.
