Click here to get an answer to your question Why carbon-12 is taken as standard.

. There are several actual reasons why Carbon-12 is taken as the standard of atomic mass measurement. By chance defining the atomic mass as 116th of the mass of a mole of oxygen comprising a natural mix of 16 O 17 O and 18 O is very close to a standard defining the atomic mass as 112 the mass of a. Carbon-12 12 C is the most abundant of the two stable isotopes of carbon carbon-13 being the other amounting to 9893 of element carbon on Earth.

This is due to two factors. The carbon-based standard represented a nice compromise. Initially the easiest measurement available was to determine the relative molecular masses of substances which are gases at room temperature.

Carbon is one of the qualifying contenders. By chance defining the atomic mass as 116th of the mass of a mole of oxygen comprising a natural mix of 16 O 17 O and 18 O is very close to a standard defining the atomic mass as 112 the mass of a mole of 12 C 3. The standard must be easily and uniformly available globally for prompt and consistent.
