No, carbon and oxygen do not have the same atomic mass. Carbon has an atomic mass of approximately 12 atomic mass units, while oxygen has an atomic mass of approximately 16 atomic mass units.

The atomic mass number of an element is the sum of the number of protons and neutrons in the nucleus of an atom. Protons have a positive charge and neutrons are neutral, together they account for the majority of an atom's mass. Electrons, which have a negative charge, are much smaller in mass and orbit around the nucleus.
The number of protons
Neutrons are used to determine the mass of an atom. By adding the number of protons and neutrons together, the atomic mass of an atom can be calculated.
The atomic number is the number of protons in an atom (which equal the number of electrons present) The atomic mass is the number of protons+neutrons in an atom
The mass of all particles of an atom added together is its atomic mass. This value is typically expressed in atomic mass units (amu).
In an atom, no. of protons = no. of electrons=atomic no. no. of neutrons=atomic mass-atomic no.
No, carbon and oxygen do not have the same atomic mass. Carbon has an atomic mass of approximately 12 atomic mass units, while oxygen has an atomic mass of approximately 16 atomic mass units.

Neutrons are used to determine the mass of an atom. By adding the number of protons and neutrons together, the atomic mass of an atom can be calculated.
The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. In the case of nitrogen, which has an atomic number of 7 and an atomic mass of 14, the number of neutrons would be 7 (14 - 7 = 7).
Atomic Mass units =]
Atomic mass refers to the total mass of the protons, neutrons, and electrons in an atom, while atomic number represents the number of protons in an atom's nucleus. Atomic mass is typically a decimal number and takes into account the mass of all the particles in an atom, whereas atomic number is always a whole number and is unique for each element.
