Question

the atomic mass or masses of an atom is actually very very small because atoms are extremely small. Today,we have sophisticated techniquee e.g. mass stratroscopy for determining the atomic masses fairly accurately . but in the nineteenth century, scientists could determine the mass of an atom relative to another by experimental means. (i)The present system of atomic mass is based on (a) Carbon-6 (b) hydrogen-1 (c)carbon-12 (d) carbon-14​

Answer 1

Answer:

ACCORDING TO THE CONCEPT THE ATOMIC WERE CALCULLATED WITH REFERENCE TO EITHER HYDROGEN OR CARBON.  BUT IN PRESENT SYSTEM , ATOMIC MASSES ARE MADE COMPARING TO CARBON-12 ATOM.
