One mole (molecular equivalent) of gold has a mass of 196.9655 g. One mole of anything equals 6.022 x 1023 items of that thing, so in 1 mole of gold there are 6.022 x 1023 atoms. The diameter of a gold atom is 3.58 x 10-10 m. If a block of gold of a mass of 202.5 g is drawn into a very thin wire of single gold atoms laid end to end, how long would the wire be? Express your answer in kilometers.

Question

One mole (molecular equivalent) of gold has a mass of 196.9655 g. One mole of anything equals 6.022 x 10²³ items of that thing, so in 1 mole of gold there are 6.022 x 10²³ atoms. The diameter of a gold atom is 3.58 x 10^-10 m. If a block of gold of a mass of 202.5 g is drawn into a very thin wire of single gold atoms laid end to end, how long would the wire be? Express your answer in kilometers.
