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 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)
What is the mass of the atom is so small that there is a measure calles the atomic?
standard
What is the dimension of atomic weight?
Atomic weight is a unit of measure whose unity value is that of the mass of a Hydrogen atom "1".
If there is a difference between a substance's atomic number and its atomic mass and which measure must be the larger number?
The atomic mass number must be higher as that represent the number of protons and neutrons in an element. Whereas only the number of protons are represented in the Atomic Number.
Does atomic mass has a positive change?
No. Atomic mass is a measure of mass, not charge.
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.
Is atomic mass electrons?
We are not using electron mass. We measure atomic mass by Mass of neutrons and protons.
How is this different from the atomic mass?
This is a question on Answers.com whereas atomic mass is a physical measure.
What special unit is used to measure atomic mass?
Atomic mass is measured by atomic mass unit(amu) . It is given by 'u' i.e. unified mass.
What unit of measure would be use to measure the mass of a proton?
You Use Atomic Mass Number
What unit of measure do you use to measure the mass of a proton?
Their mass is measured in atomic units 1 atomic unit is 1.660538782×10−27 kg A Proton has a mass of 1.007276466 u (u is the symbol for Atomic Mass) A Neutron has a mass of 1.008664915 u
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)
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.
What units are used to measure the mass of atoms?
AMU=Atomic Mass Unit
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.
What is the earths atomic mass?
Since the Earth is not a single atom, nor a collection of similar atoms, it does not have an atomic mass. Atomic mass is a measure of how much matter is contained by a specific atom.
