What's Your Question?
Answer
12g/Avogadro no. =the mass of one carbon atom. A carbon atom has 12 nucleons and each nucleon is about 1 mass unit. Reciprocal of Avogadro no. is called Avogram.
Answer

Reciprocal of Avagadro No.=1/6.022 X 1023 = 1.66 x10-24g

It is equivalent to 1 amu and also have approximately same as mass of proton.

Reciprocal of Avagadro No.=1/6.022 X 1023 = 1.66 x10-24g

It is equivalent to 1 amu and also have approximately same as mass of proton.

Answer
1 amu is defined as one twelfth of the mass of one carbon -12 atom
Answer
1amu is equal to 1/12th part of an atom of carbon 12.
Answer
12 grams of carbon is equal to same as mole by giving 6.022×10,23 so ultimately 12g / avagadro = mass of one carbon atom
