Best Answer

The unit of Atomic Mass is defined as 1/12 of the rest mass of the Carbon 12 atom and it is called a.u.m. or Da, read Dalton, from the name of the scientist that first introduced it.

Thus the rest mass of Ca 12 is exactly 12, while the rest mas of H is about 1.

The mass of many proteins is from 10 to 300 kDa.
