### How many grams of copper atoms are needed to supply the same number of atoms as does 235 grams of iron?

The number of atoms in a given mass of metal may be calculated
by dividing the mass by the gram atomic mass, then multiplying by
Avogadro's Number. The gram atomic masses of iron and copper are
55.847 and 63.546 respectively. Since Avogadro's Number is
constant, the required mass m of copper atoms can be found from the
equation m/63.546 = 235/63.546, or m = 235 X (63.456/55.847), or
267 grams of copper, to the justified number of significant
digits.
