What is the atomic mass made up of?
The atomic mass is made up of protons and neutrons (which is basically the nucleus.)
Mass is a measurement of the amount of matter in an object. An atom has mass. The atomic mass is made up of protons and neutrons because both of these particles make up the atom's nucleus and have mass. Electrons also make up an atom, but their masses are so small that they are not usually calculated in with the atomic mass.
If an element has an atomic number of 8 and an atomic mass of 14 then how many neutrons does it have?
the atomic number is the number of protons the atomic mass is the grams per mol in that element the charge of an atom's nucleus... that's the atomic mass, because the nucleus is made up of PROTONS and NEUTRONS, so subtract the atomic number from the atomic mass to get the neutrons... i might still not be answering your question, so sorry if i didn't
There are no 'nucleons' in an Oxygen atom. You mean 'neutrons'. As all the mass of an atom is in its nucleus (made up of 'protons' and 'neutrons') and as the Atomic Number is the count of how many 'protons' there are, if you subtract the Atomic Number form the Atomic Mass, you get the number of 'nutrons'. 17-8=9.
The molar mass is the mass of a molecule - sum of the masses of contained atoms, expressed in grams. The atomic mass is the mass of an isotope expressed in unified mass atomic units. The atomic weight is the mass of a chemical element (taking into account its isotopes) expressed in unified mass atomic units; also known today as relative atomic mass. IUPAC maintain the term (standard) atomic weight.
Atomic weights refer to ATOMS. Water is a MOLECULE made up of 3 atoms, it therefore does not have an atomic weight, it has a MOLECULAR weight. You calculate the molecular weight by adding up the atomic weight of all the atoms in the molecule. Waster is made up from 1 atom of Oxygen (atomic weight 16) and 2 atoms of Hydrogen (atomic weight 1) 16+1+1 = 18 The molecular weight of water is therefore…
An atomic mass is the mass without any changes to it. average atomic mass is is when you average it up that's all. Added: Atomic mass is the average of the masses of the naturally existing (i.e. mixture of) isotopes of one specific element. The atomic mass number is the sum of the protons and neutrons in the nucleus of an atom (specific for one specific isotope).
What is the mass of one mole of Al2O3 if aluminum has an atomic number of 13 and an atomic mass of 26.98 and oxygen has an atomic number of 8 and an atomic mass of 16.00?
Well first of all a molecule doesn't have an atomic mass it has a molecular mass. It's molecular mass is found by adding up the atomic masses of all the elements that make up the molecule. These atomic masses are found on a periodic table. For example water has a formula of H20. This means it is made of 2 hydrogen atoms and 1 oxygen atom. Hydrogen has an atomic mass of 1 g/mol while…
