What unit of measure is used to measure atomic weight?
expressed in unified atomic mass unit, amuHowever, for practical purposes in the laboratory the relative atomic mass is used so the unit would be gram. (Relative atomic mass compares the mass of all elements to that of the carbon-12 isotope taken as exactly 12)
Does 8 protons have a weight of one atomic mass unit?
The mass of eight protons is approx. 8 amu.
What is one twelfth of the mass of the carbon 12 atom?
the answer is the atomic mass unit
What is relationship between the formula weight of a substance and its molar mass?
Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .
What is the standard for atomic mass unit called?
One twelfth (1/12) the mass of a carbon-12 atom is one atomic mass unit (amu, or just u).
What is the difference between atomic mass and relative atomic mass?
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.
The unit for atomic mass?
"It is defined as one twelfth of the rest mass of an unbound atom of carbon-12 in its nuclear and electronic ground state..." (Wikipedia, atomic mass unit, retrieved 2011-01-19). An atomic mass unit is approximately the mass of a neutron, or of a proton.
Is it true that the mass of a proton is about one atomic mass unit?
no
In 4gm of Ag .calculate weight of one atom of Ag?
That should be mass, not weight. The mass of one atom of Ag doesn't depend on the size of the sample. Also, you can't "calculate" the mass of one atom from the information provided. You can look it up - or you can look up the atomic mass of Ag, and multiply it by the atomic mass unit.
Is the mass of one electron equal the the mass of one atomic mass unit?
Since "amu" stands for "atomic mass unit" ... maybe. "mass unit" is kind of a meaningless phrase; it could refer to grams, kilograms, slugs, or whatever.
Atomic mass unit is equal to what?
Unified atomic mass unit, a small unit of mass used to express atomic and molecular masses. The atomic mass unit is equal to one-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
What is unit for atomic masses?
Atomic mass is a mass, the SI units of mass are kg. The atomic mass unit is equal to one-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg. Atomic mass unit is recognized now as a non-SI unit.
