Question

How many atoms are there along a 43.0 cm line?

Answer 1

5,343,564,892,635,438,761,258,875,582,45... atom in a 43 cm line

well probly more sorry cant help u i dont know were u got this from but its just 2 hard for anyone lol

Answer 2

taking copper for example as the sphereical radii differs by element.

diameter of copper atom = 2.83 x 10^-9 m

43 cm = .43m

(1 atom / 2.83 x 10^-9 m)(.43m) = 1.52 x 10^8 atoms or approximately 150 million copper atoms.  

theoretically of course as atoms don't line up exactly side by side in a 1 atom thick line.

additional:  i made my initial diameter estimation by using standard density but it turns out i was off by a bit  according to wikipedia.  they list the atomic diameter at 138 pm which is 138 x 10^-12 m

recomputing 1 atom / 138 x 10^-12m (.43m) = 3.12 x 10^8 atoms or 312 million atoms of copper

Answer 3

43 cm line of air or lead? or just a line of atoms? I've heard a million would be the thickness of your fingernail..  not sure about 43 cm.

Answer 4

There are so many atoms in a line that there is no way to be able to count them, sense there so small you could off by millions so no, there is no way to tell exactly how many atoms are in a 43.0 cm line. sorry

Answer 5

i really do not know

Answer 6

uh.... not 2?
