here are 2.619 x 10^22 atoms in 1.000 g of sodium. Assume that sodium atoms are spheres of radius 1.86 Å and that they are lined up side by side. How many miles in length is the
line of sodium atoms?

aaronq · Answer

can't do it in miles, cuz well, thats just not scientific ;) but i can give you a hint my american friend,

1 angstrom = 1*10^-10 m

or

1 m = 10,000,000,000 angstroms
