They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
No. The Atomic Mass of carbon is 12.0107 amu. The atomic mass of oxygen is 15.9994 amu.
The same way you calculate the atomic mass of other elements.
its the same as the mass number e.g. oxygen(-16) is 16, carbon-12 is 12 but carbon-13 is 13 because it has an extra neutron i think anyway Really? I thought that the relative istopic mass was a ratio of the average atomic mass of the element compared to the average atomic mass of carbon. For example chlorine has an average atomic mass of 37 and carbons atomic mass is 12 so its 37 divided by 12 which is about 3:1.
No. They have different masses, but the same atomic number. Carbon-12 has a mass number of 12 and atomic number of 6, and carbon-14 has a mass number of 14 and atomic number of 6. The difference in mass number is due to different numbers of neutrons. Carbon-12 atoms have 6 neutrons and carbon-14 atoms have 8 neutrons.
Carbon and oxygen or two different elements, with different masses.
look at a periodic table, it should say what the atomic masses are for each atom. then, simply add the mass of Carbon (C) and 2x Oxygen(O). the same method works for any other compound

No all oxygen atoms do not have the same mass as you can get isotypes of the same element which are still called the same except that they can have more or less neutrons than the standard model this is why the weight is refered to as an average mass
They don't. Sulphur has about twice the atomic mass of oxygen.

The expression atomic mass is used only for isotopes; the atomic mass is the mass of an atom expressed in unified atomic mass units - (1 amu = 1/12 atomic mass of carbon-12).For elements the expression is atomic weight; the unit is the same.

No, the Atomic Mass is the full complete mass while the mass # is just the whole number. For example: carbon's atomis mass is 12.011 and the mass # is 12.
Because the mass of carbon is not the same as that of oxygen.
An isotope is simply a certain element with a different atomic mass, for example carbon 12 is the same element as carbon 13 because it has the same number of protons, but it has an atomic mass of 12 because it has a different number neutrons. On the periodic table, the atomic mass labeled is normally the average atomic mass, or the mass of the most stable isotope. So to answer your question two different isotopes of the same element have a different number of neutrons, but the same number of protons and electrons.
