so the mass of an atom is determined by the number of protons and neutrons in an element. For a given element, the number of protons is the same but the number of neutrons can vary (an element can have various isotopes). Therefore, the average Atomic Mass of an element is simply a weighted average of the masses of all the isotopes of that element.
(a weighted average means that how common an isotope is is taken into account when incorporating it into the average, so rare isotopes will not count as much as common isotopes)

What is one twelfth of the mass of the carbon 12 atom?
the answer is the atomic mass unit
What describes the definition for the atomic mass of an element?
the atomic mass is the mass of an atomin the table of elements each element has its own specific box. the atomic mass is listed under the elemnts symbolEX. 2HE4.00
What does the word weighted mean in the definition of relative atomic mass?
In the definition of relative atomic mass, the term "weighted" refers to the consideration of the abundance of each isotope of an element when calculating its average atomic mass. Instead of simply averaging the masses of all isotopes, the relative atomic mass is determined by multiplying the mass of each isotope by its relative abundance, then summing these values and dividing by the total abundance. This ensures that isotopes that are more prevalent in nature have a greater influence on the final average atomic mass.
How many moles are in 5.87 g Ni?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Nitrogen's atomic mass is 14.007 grams.
How many gram does one mole of helium gas weighs?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
What is one twelfth of the mass of the carbon 12 atom?
the answer is the atomic mass unit
What is the best definition for the term amu?
Atomic Mass Units.atomic mass unit
What is the AMU of carbon?
AMU stands for atomic mass units; the number of units an element has is called its atomic mass. The atomic mass of carbon is exactly 12, by definition.
What describes the definition for the atomic mass of an element?
the atomic mass is the mass of an atomin the table of elements each element has its own specific box. the atomic mass is listed under the elemnts symbolEX. 2HE4.00
How many atomic mass units are there in carbon-12?
12 by definition.
What is Carbon-12 atomic mass?
12. The number 12 refers to the atomic mass. More precisely, to the sum of neutrons + protons; but this is usually close to the atomic mass. In the case of carbon-12, it is exact, by definition.
What does the word weighted mean in the definition of relative atomic mass?
In the definition of relative atomic mass, the term "weighted" refers to the consideration of the abundance of each isotope of an element when calculating its average atomic mass. Instead of simply averaging the masses of all isotopes, the relative atomic mass is determined by multiplying the mass of each isotope by its relative abundance, then summing these values and dividing by the total abundance.

How come the relative atomic mass can be a fraction?
The relative atomic mass is the mean mass of the isotopes of an element. Since, by definition, these have different numbers of neutrons, their masses are different. This results in fractional values.
How many gram does one mole of helium gas weighs?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
What is atomic mass unit and how is it derived?
1 atomic mass unit is equivalent to the 1/12 the mass of a carbon-12 atom at rest. This is not considered an si unit because it is defined by a definition and not experimentally
What is the definition of 'Atomic Mass'?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
