Does au passé?

AU is an abbreviation for a number of things. It can refer to Australia, the Angstrom Unit, the Astronomical Unit, and the Arithmetic Unit. In addition, it can refer to Auburn University and Air...

Au is the place in Vorarlberg, Austria (the one located at 47d19m22s N, 9d58m33s E)

n(Au)= 1.5g/M(Au) = 1.5/196.97 = 0.00761537mol n(Au) = No(Atoms)/N(a) therefore N(Atoms)=n(Au) x N(a) N(atoms) = 0.00761537mol x 6.02x10^23mol*-1 N(atoms) approximatly equals 4.6x10^21 atoms

An au is an astronomical unit, or how far light will travel in a year.

1 mol = 6.02 x 10^23 2.88 x 1023 atoms = 2946.24 atoms = (2946.24) / (6.023 x 10^23) moles = 4.89 x 10^-21moles Or if you meant=> 2.88 x 10^23 atoms = (2.88/6.02) moles = 0.478 moles (3 s.f)
