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 mass of an atom expressed in atomic mass units. The atomic weight of an element having more than one principal isotope is calculated both from the atomic masses of the isotopes and from the relative abundance of each isotope in nature.
