relative Atomic Mass
relative atomic mass
when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )
The gram atomic mass, also known as molar mass, is the mass of one mole of an element or a compound in grams. It is numerically equal to the atomic or molecular weight of the substance in atomic mass units.
The atomic mass number of nitrogen is 14.0
No: 14.0067 is the gram atomic mass of nitrogen.
The average atomic mass is weighted by the most common isotopes and their relative abundance.
The number of atoms in a given relative mass of each type of atom depends on the atomic mass of the elements involved. Since atomic mass is expressed in atomic mass units (amu), a heavier atom will have fewer atoms in the same mass compared to a lighter atom. For example, one gram of hydrogen, which has a low atomic mass, contains significantly more atoms than one gram of lead, which has a much higher atomic mass. Thus, the number of atoms varies inversely with the atomic mass of the element.
the relative atomic mass for the element potassium is 39.0983
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
Gram Atomic Mass
The relative atomic mass of magnesium is approximately 24.305.
Approximately 4.01
