Answer:Atomic Mass
An atom is such small a particle that it cannot be seen or isolated. Therefore, it is impossible to determine the actual mass of a single atom by weighing it. However, Avogadro’s hypothesis finally solved the problem. He took equal volumes of two different gases under similar conditions of temperature and pressure. He then weighed them.
Surprisingly, the ratio of their masses was equal to the ratio of their single molecules. Thus, though the actual masses of the atoms could not be determined, their relative masses could be determined. If the atomic mass of hydrogen is taken as 1, the relative atomic mass of oxygen is 16.
Initially, scientists obtained the atomic masses of all the elements by comparing with the mass of hydrogen taken as 1. However, the problem was that the atomic masses of most of the elements came out to be fractional in this method. Therefore, carbon is taken as the reference for the determination of atomic masses.
