Potassium (atomic mass 39.10 g/mol) crystallizes in a body-centered cubic lattice, and the length of the edge of a unit cell is 532.8 pm. What is the density of K? ______ g/cm^3
Added by Felipe G.
Step 1
First, we need to find the volume of the unit cell. The volume of a cube is given by V = a^3, where a is the length of the edge. In this case, a = 532.8 pm. We need to convert this to cm: 532.8 pm * (1 cm / 10^10 pm) = 5.328 * 10^-8 cm. So, the volume of the unit Show more…
