WebThus the mass of a cubic cm of copper is $8920\times 10^{-6}$ kg. Divide this by the mass of an atom to find, approximately, the number of atoms. Equivalently, first find the number of atoms in $1$ cubic metre, by dividing the mass by the mass of an atom. Then divide by $10^6$ to find the number of atoms in $1$ cubic centimetre.
