Carbon-12 is considered as unit to calculate atomic mass. Carbon-12 is an isotope of carbon. The relative mass of all atoms are found with respect to C-12.
One atomic mass = 1/12 of the mass of one atom of C-12.
This means atomic mass unit = 1/12th of carbon-12
Thus atomic mass is the relative atomic mass of an atom with respect to 1/12 th of the mass of carbon-12 atom. ‘amu’ is the abbreviation of Atomic mass unit, but now it is denoted just by ‘u’.
The atomic mass of hydrogen atom = 1u.
This means one hydrogen atom is 1 times heavier than 1/12th of the carbon atom
