26.98 atomic mass units
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
Aluminium oxide Al2O3 has a formula mass of: (2X 26.981538) + (3 X 15.9994) = 128.94 = 129 to nearest atomic mass unit.
The atomic mass unit is used to express the measure of the atomic mass.
AMU stands for atomic mass unit. 1 amu is 1.66053892 times 10 up to the negative 27 kilograms.
the answer is the atomic mass unit
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
Aluminium oxide Al2O3 has a formula mass of: (2X 26.981538) + (3 X 15.9994) = 128.94 = 129 to nearest atomic mass unit.
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
Aluminum's atomic mass is 26.9815386,but if rounded up,it is 27.

Atomic Mass Unit (amu)
Atomic mass is measured in a unit called an "atomic mass unit". This unit is defined as 1/12 of the mass of a carbon-12 atom at ground state.An atomic mass unit is approximately 1.66053886 x 10-27 kg.Atomic mass is measured in atomic mass units (amu) and Daltons.
the answer is the atomic mass unit
The atomic mass unit is 1/12 from the atomic mass of the isotope 12C.
The Atomic Mass unit is 1/12 from the atomic mass of the isotope carbon-12, in steady state.
