To find the density of the element that crystallizes in a face-centered cubic (FCC) lattice, we can follow these steps: ### Step 1: Convert the cell edge length to centimeters The given cell edge length (a) is 400 picometers (pm). We need to convert this to centimeters (cm). \[ a = 400 \, \text{pm} = 400 \times 10^{-12} \, \text{m} = 400 \times 10^{-10} \, \text{cm} \] ...
