The average mass of a manganese atom is 54.94 amu or 9.12 x 10⁻²⁶ kg.
One unified atomic mass unit is approximately the mass of one nucleon (proton or neutron).
The unified atomic mass unit (amu) is a standard unit of atom mass.
One unified atomic mass unit is approximately the mass of the one nucleon (1.66·10⁻²⁷ kg)
Ar(Mn) = 54.94 amu; a relative atomic mass of manganese atom
m(Mn) = Ar(Mn) x 1.66·10⁻²⁷ kg
m(Mn) = 54.94 x 1.66·10⁻²⁷ kg
m(Mn) = 91.2 x 1.66·10⁻²⁷ kg
m(Mn) = 9.12 x 10⁻²⁶ kg; the average mass of a manganese atom
