Best Answer: Ok...here it goes... Socrates was noted for his dedication to careful reasoning. He sought genuine knowledge rather than mere victory over an opponent. He employed the same logical tricks developed by the Sophists to a new purpose, the pursuit of TRUTH.
The atomic mass of a specific atom or molecule is determined by using an experimental technique called mass spectrometry. This technique separates the different isotopes of atoms to allow determination of the percent abundance or isotopic composition of the element in the given sample.
The units in which the mass of an atom are expressed are atomic mass units. At one time, the lightest atom was assigned a mass of 1 amu and the mass of any other atom was expressed in terms of this standard. Today atomic mass units are defined in terms of the 12 C isotope, which is assigned a mass of exactly 12.000...
