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.
atomic mass unit. A unit of mass equal to 1/12 the mass of an atom of the most common isotope of carbon (carbon 12), which is assigned a mass of 12. A hydrogen atom has a mass of 1 atomic mass unit since its mass is 1/12 the mass of carbon 12.
