Question

What will be the mass of one atom of C-12 in
gram?​

Answer 1

Answer:

It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, 1.992646547 × 10−23 gram, which is assigned an atomic mass of 12 units. In this scale 1 atomic mass unit (amu) corresponds to 1.660539040 × 10−24 gram.

Explanation:

Answer 2

Mass of 1 mole = 12gm

Mass of 6.022×10²³ atom=12gm

mass of 1 atom = 12 / 6.023×10²³

=1.993×10-²³ gm
