The mass of any material will depend on two factors:
- Its Volume
- Its relative density
- The gravity of the place you are trying to find this out!
The relative density for Aluminium is 2.6995g/cm³ at room temperature.
So for every cubic cm of aluminum it will weigh 2.6995 grams.
Say for example you have 10 cubic cm of aluminum, it will weigh 26.995g.
We need to convert this figure in grams to standard units (the kilogram) so divide the 26.995 by 1000 to give us 0.026995Kg. Multiply this by the 9.81m/s for the gravity of the earth. This gives us a mass of 0.26482095 Newtons.
Obviously this figure will vary depending upon how much Aluminium you have...
To find the mass we need to multiply this weight by the

What is the average atomic mass compared to atomic mass?
The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the periodic table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.
What is the weighted average atomic mass of bromine?
The weighted average atomic mass of bromine is approximately 79.904 u. This value is calculated based on the natural abundance of bromine's isotopes.
What is the difference between mass number relative atomic mass and average atomic mass?
The mass number is the total number of protons and neutrons in an atom's nucleus. Relative atomic mass is the weighted average mass of all the isotopes of an element, taking into account their natural abundance. Average atomic mass is the weighted average mass of an element's isotopes in a given sample, considering their abundance in that sample.
Weighted average mass of the mixture of its isotopes?
The weighted average mass of a mixture of isotopes is calculated by multiplying the mass of each isotope by its natural abundance, and then summing these values together. This gives a more accurate representation of the overall mass of the isotopes in the mixture, taking into account their relative abundances.
Why do elements which exists as isotopes have fractional atomic mass?
Each isotope of an element has a different Atomic Mass, so an average is taken of all the isotopes, but the average is weighted because the natural abundance (%) of each isotope is factored in. If hydrogen-1 is much more abundant than deuterium and tritium, then the weighted average will be closer to 1 than 2 or 3 but not a whole number. The following equation shows how percent abundance factors into the weighted average. (atomic mass A)(X% abundance) + (atomic mass B)(Y% abundance)...=(weighted average of all isotopes of the element)(100% abundance)

What is center of the mass?
It is basically the "average location" of all the masses. A sort of weighted average, actually.

Is an average mass of the different isotopes of the element?
The average atomic mass of an element is the weighted average of the masses of its isotopes, based on their abundance in nature. It is calculated by multiplying the mass of each isotope by its relative abundance, then summing these values together. This average mass is given on the periodic table.

Which best describes the definition for the atomic mass of an element?
The atomic mass of an element is the average mass of an element's isotopes, weighted by their natural abundance. It is expressed in atomic mass units (u) and is often close to the mass number of the most abundant isotope of the element.
