Question

Which of the following represents 12 u?
1 point
(a) Mass of 1 hydrogen atom
(b) Mass of C-12 atom km
(c) Mass of 0-16 atom
(d) 1/12th of mass of C-12 atom.​

Answer 1

Answer:

b) massof c-12 atom

Explanation:

Answer 2

Answer:

It's (b) Mass of C-12 atom

Explanation:

Mass of C- 12 atom represents 12 u (amu).

Because mass of 1 hydrogen atom is 1u(amu) .

also the mass of O-16 atom is 16u

and 1/12th of mass of C-12 represents 1u(amu).

Therefore, as 1/12th of mass of C-12 represents 1u it's clear that 12 u represents Mass of C-12 atom. The above image shows some information which might be useful.
