what is the mass (in amu) of a single carbon-12 atom? | …

9/10/2008· it is 12. amu is defined as 1/12 the weight of a carbon atom. this is because carbon has 12 protons, so its supposed to roughly be the weight of a single atom. This is not strictly true because binding energy in an atom changes with size and since energy equals mass its slightly different, but you dont have to worry about that.

Average atomic mass (video) | Khan Academy

The average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon …

What is the mass of the hydrogen atom? - Answers

The mass of a hydrogen atom is 1.66 x 10^(-27) kg. Further, any atomic weight can be derived by dividing its molar mass by Avogardro''s nuer.

Expressing the mass of an atom

The mass of a hydrogen atom is 1.6727 10 kg. To avoid having to work with such small nuers all the time, the tradion of using a relative atomic mass scale was started. Although such a relative scale has undergone several incarnations, in 1961, by international agreement, a scale was settled upon.

Atomic Properties - City University of New York

The atom with the smallest mass is the hydrogen atom; its mass is about 10-27 kg. The masses of other atoms go up to about 200 times this. The nucleus of an atom is about 10 -15 m in size; this means it is about 10 -5 (or 1/100,000) of the size of the whole atom.
