Question

The diameter of a copper atom is approximately 2.28e-10 m. 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. What is the mass of one copper atom, in kg? How many copper atoms are there in a cubical block of copper that is 4.4 cm on each side? What is the mass of the cubical block of copper, in kg?

Answer 1

The mass of one copper atom, in kg, is 1.09e-25 kg. There are 2.13e+20 copper atoms in a cubical block of copper that is 4.4 cm on each side. The mass of the cubical block of copper, in kg, is 1.43kg.
