How many atoms are in 3 kg of copper
WebThere are $(100)^3$ cubic centimetres in one cubic metre. Thus 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.
