Video lesson showing how to calculate atomic mass from the naturally occuring isotopes of an element using relative natural abundance and isotopic mass.
∴ Gram molecular mass of oxygen = 32 g Learn how to calculatethe number of mole and equivalent weight. Solved Example For You Q: The specific heat of a metal of atomic mass 32 is likely to be: 0.25 0.24 0.20 0.15 Solution: Specific heat = 6.4/atomic mass ...
In the Bohr Model image, only the black and white particles found in the nucleus of the atom would be part of the calculation done to determine the mass number. Bohr Model showing nucleus Isotopes vary in the number of neutrons that are in the nucleus of a particular element. This result...
A hydrogen-1 atom has a mass of 1.007 u (or Da or amu). A carbon-12 atom is defined as having a mass of 12 u. The largest known protein, titin, has a mass of 3 x 106Da. AMU is used to differentiate between isotopes. An atom of U-235, for example, has a lower AMU than ...
The number and mass of electrons is not included in an atomic mass calculation because the mass of the electron is infinitesimal compared to that of a proton or neutron. Basically, electrons don't significantly affect the mass of an atom....
atomic mass can also refer to the average mass in a group consisting of atoms. Also, electrons have much lesser weight than both protons and neutrons. Consequently, electrons don’t really matter in the calculation. Therefore, atomic mass effectively is the sum of masses of neutrons and protons...

For example helium has an atomic mass of 4.0026. That was obtained by adding the amount of protons and neutrons in a helium atom together. On the other hand 4.0026 is also the weight in grams of 1 mole of helium. Since 1 mole contains the exact same number of atoms regard...
More Commonly Known as Relative Atomic Mass Atomic massis used interchangeably with atomic weight, although the two terms don't mean precisely the same thing. Another issue is that "weight" implies a force exerted in a gravitational field, which would be measured in units of force, like newtons...
