Mass of 1 H atom

1/12th of the mass of 1 C - 12 atom

1/12th of the mass of 1 C - 13 atom

1/12th of the mass of 1 C - 14 atom

​

Answer 1

Answer:

1/12th of the mass of 1 c - 12 atom

Explanation:

An amu is defined as exactly 112 of the mass of a carbon-12 atom and is equal to 1.6605 × 10−24 g.

Answer 2

On the periodic table the mass of carbon is reported as 12.01 amu. This is the average atomic mass of carbon. No single carbon atom has a mass of 12.01 amu, but in a handful of C atoms the average mass of the carbon atoms is 12.01 amu.
