what is the amu of Bi?
« on: September 03, 2007, 09:53:01 PM »
Hi, how do i calculate the mass of an atom of Bi in atomic mass units?  Is this the right answer: mass of Bi/mass of 12C *12 amu = 208.980g/12.01g * 12amu = 208.8060 amu?

The average mass of any atom in amu is the atomic mass listed on the periodic table.  If you want the mass of a particular atom of Bismuth, you must specify the isotope that you want as all of the isotopes have a different mass.
