The mass of 1 atom of copper metal in the given face-centered cubic structure is determined as 1.054 x 10⁻²² g.
Mass of 1 atom of copper
The mass of 1 atom of copper is calculated as follows;
mass of 1 atom of copper = molar mass of copper / Avogadro's number
substitute the value of molar mass of copper and Avogadro's number;
mass of 1 atom of copper = (63.5 g/mol) / (6.023 x 10²³)
mass of 1 atom of copper = 1.054 x 10⁻²² g
Thus, the mass of 1 atom of copper is determined as 1.054 x 10⁻²² g.
