Usually you don't "calculate" the atomic mass, you measure it (okay, there are some calculations involved). You can approximate the atomic mass by adding the number of protons and neutrons; at this level of precision you can disregard the electrons since they're so light compared to the neutrons and protons, and the answer won't be "right" anyway because you're also ignoring binding energy.
The unit is formally "u" or "Da" (daltons). 1 u = 1 Da = 1/12 the mass of an isolated carbon-12 atom in its nuclear and electronic ground state. For some reason, biologists and biochemists seem to have embraced the "dalton" more rapidly than chemists, who generally still use the archaic abbreviation "amu" even when what they really mean is u (1 amu is approximately 1 u, but there was some ambiguity in the term because it was defined differently in chemistry and physics).
The Atomic Mass of an element is calculated by taking the weighted average of the masses of its isotopes, based on their relative abundance. The unit of measurement for atomic mass is the atomic mass unit (amu) or unified atomic mass unit (u). 1 amu is defined as 1/12th the mass of a carbon-12 atom, which is approximately equal to the mass of a proton or a neutron.
The atomic mass unit (amu) is a unit of mass used to express the average mass of an atom or molecule. To calculate the atomic mass unit of gold (Au), you would look at the atomic mass of gold on the periodic table, which is approximately 197 amu.
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.
A neutron has an approximated weight of 1 a.m.u. (the standard unit for atomic mass measurement).
the answer is the atomic mass unit
Atomic mass unit
The atomic mass unit (amu) is a unit of mass used to express the average mass of an atom or molecule. To calculate the atomic mass unit of gold (Au), you would look at the atomic mass of gold on the periodic table, which is approximately 197 amu.
It is amu or AMU.
atomic units. A proton has a mass of 1 atomic unit, and so does a neutron. the mass of an electron is very small, and almost negligible
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.
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.
Atomic Mass Unit (amu)
A neutron has an approximated weight of 1 a.m.u. (the standard unit for atomic mass measurement).
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 carbon-12, in steady state.
