What is the difference between atomic mass and relative atomic mass?

∙ 13y ago
Atomic mass is the measure of a mass of one atom in relation to 1/12 mass of Carbon 12 atom and measured in Atomic Mass unit(amu) or Dalton unit or grams/mol.
Relative atomic mass is also the relative mass but does not have a unit but a ratio number.

What is the atomic mass on the periodic table?
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
What is the relative atomic mass of potassium?
the relative atomic mass for the element potassium is 39.0983
Why atomic mass is called relative atomic mass?
Atomic mass is so small you can't actually measure it. So, just like carbon dating, you have to use a relative mass.
Why is the krypton atomic mass not determined?
The relative atomic mass is 83.798. So where did you get that it is not determined.
What is the relative atomic mass of sodium?
Sodium is a meta element. Atomic mass of it is 23.
What is the difference between mass number relative atomic mass and average atomic mass?
What is the atomic mass on the periodic table?

What is the difference between atomic mass and atomic mass unit?
The atomic mass unit is used to express the measure of the atomic mass.
What is the difference between relative isotopic mass and relative atomic mass?
Atomic Mass is 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.Relative atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12.Relative isotopic mass is the mass of an atom of an isotope of an element compared with one-twelfth the mass of an atom of carbon-12.Thus an element will have ONE Relative Atomic Mass but there may be MANY individual Relative Isotopic Masses for an Element (depending on how many Isotopes it has).
What does the relative atomic mass of an element tell us about the relative abundance of an isotope?
None. The relative abundance of isotopes is used to calculate the Average Mass (by multiplying the Atomic Mass of the isotopes by their relative abundancies and adding the products together) while the Atomic Mass is simply the number of protons plus the number of neutrons.
What is the relative atomic mass of potassium?
the relative atomic mass for the element potassium is 39.0983
Why Cu has a relative atomic mass?
All elements have an atomic mass relative to 12C having a mass of 12.
What is the difference between the atomic number and the atomic mass?
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
What is the atomic mass in Hindi?
The atomic mass (ma) is the mass of a specific isotope, most often expressed in unified atomic mass units.[1] The atomic mass is the total mass of protons, neutrons and electrons in a single atom.[2]The atomic mass is sometimes incorrectly used as a synonym of relative atomic mass, average atomic mass and atomic weight; these differ subtly from the atomic mass. The atomic mass is defined as the mass of an atom, which can only be one isotope at a time and is not an abundance-weighted average as in the case of atomic weight. In the case of many elements that have one dominant isotope the actual numerical similarity/difference between the atomic mass of the most common isotope and the relative atomic mass or standard atomic weights can be very small such that it does not affect most bulk calculations-but such an error can be critical when considering individual atoms. For elements with more than one common isotope the difference even to the most common atomic mass can be half a mass unit or more (e.g. chlorine). The atomic mass of an uncommon isotope can differ from the relative atomic mass or standard atomic weight by several mass units.
