The number of atoms in a sample is directly proportional to the mass of the sample and inversely proportional to the atomic mass of the element. If two samples of elements have the same number of atoms and the same mass, then the atomic masses of the two elements must be the same. This means that the two elements must have the same number of protons and electrons, which means that they must be the same element. Therefore, all of the choices are true.
