To calculate the density of an element that crystallizes in a face-centered cubic (FCC) lattice, we can follow these steps: ### Step 1: Understand the given data - The edge length of the FCC unit cell (a) = 250 pm = \(250 \times 10^{-10}\) m = \(2.5 \times 10^{-8}\) cm. - The total mass of the element = 300 g. - The total number of atoms = \(2 \times 10^{24}\) atoms. ### Step 2: Calculate the number of moles of the element ...
