Approximately what is the radius of a copper atom? Is it , , , , or

m?

The diameter of a copper atom is approximately . The mass of one mole of copper is 64 grams. Assume that the atoms are arranged in a simple cubic array. Remember to convert to S.I. units.

(a) What is the mass of one copper atom, in kg?

(b) How many copper atoms are there in a cubical block of copper that is 4.6 cm on each side?

(c) What is the mass of the cubical block of copper, in kg?
