A gold atom has a diameter of 2.88 X 10^-10 m. Suppose the atoms in 1 gold bar of gold (standard mass of one gold bar is 12.4 kg) are arranged just touching their neighbours in a single straight line.
a) Determine the length of the line.

b) Given that the surface area of the earth is 5.1 X 10^14 m^2, what would be the h of the shell of gold atoms that would cover the earth using the amount of gold from part (a)
