“Suppose you had a mole of gold atoms (radius=144pm) and could link the atoms together like a string of pearls.

How many of these gold necklaces could you make using 1 mole of gold atoms so that each necklace would stretch from the earth to the sun? (Distance from earth to the sun =92.58 million miles; 1 mile=1.6093km).”

(144×10^-15)x6×10^23=864×10^8m

to the sun
92.6×10^6×1.6=148×10^6km
which is
148×10^9m

then 148×10^9/864×10^8=0.17×10^1
or 1.7moles of gold.

So, I shouldn’t use the radius given to find the diameter?
