Lösung:

1. The idea: about. 60% The Land surface with Water Covered, Radius of the earth about. 6000 km, Average Depth of water about. 3 km
2. all These Assumptions Delivery a Volumes of 0.814·10⁹ km³
3. This is Wikipedia. has almost This equal to Volumes:
       V = 1.338·10⁹ km³ = 1.338·10²¹ Litre
       In the the following will be with to the The value of Wikipedia Continued calculated
4. 1 g Au → n(Au)=1g/197g/mol= 1/197 mol
5. 1/197 mol ≙ 3.057·10²¹ Au-Atoms
6. 3.057·10²¹ / 1.338·10²¹ = 2.28 Atoms for each Litre
