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.
To find the atomic mass of CO2, you need to identify the atomic masses of each element in the compound and then add them together. The atomic mass of carbon (C) is 12.01 amu, and the atomic mass of oxygen (O) is 16.00 amu. In CO2, there are two oxygen atoms, so you would calculate the atomic mass by adding 12.01 amu (carbon) to 2x16.00 amu (oxygen) for a total of 44.01 amu.
The same way you calculate the atomic mass of other elements.
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.
The atomic mass unit (amu) of a carbon isotope refers to the average mass of carbon atoms within that isotope relative to the mass of a carbon-12 atom. Carbon has several isotopes, including carbon-12, carbon-13, and carbon-14. The difference in amu values for carbon isotopes is due to the presence of different numbers of neutrons in the nucleus, which affects the overall mass of the isotope.
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

isotopes of carbon are atomic no. 6 mass 12 , atomic no.6 mass 13 , atomic no. 6 mass 14
The same way you calculate the atomic mass of other elements.
They don't. Sulphur has about twice the atomic mass of oxygen.
an oxygen and a hydrogen atom do not weight the same
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.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Carbon and oxygen or two different elements, with different masses.
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.
The difference would lie in their atomic mass. The number of neutrons in an atom affects its atomic mass, which is the sum of the protons and neutrons in the nucleus. Therefore, two atoms of carbon with the same number of neutrons would have the same atomic mass.
