Length generated by all atoms contained in 1 gram of iron

[joebox]

Hi,

I tried to calculate the distance resulting from Na iron atoms contained in 1 g. scaled in meters and by juxtaposing them in a single thread (segment).

I did the following calculation with:
Atomic radius : 140 E-10 meters
Na : 6 E23 atoms in 56 g. of iron

=> ( 2 x 140 E-10 x 6 E23 )/56 = 3 E14 meters...

In other words, 300 milliard KM with only 1 gram of iron... so I must have made a (or several) mistakes

Thank you for your help !

Jean-Marc

No mistake, the number is huge as atoms are tiny - you get an extremely long, extremely thin line.
