Giving out the most points I can for these questions: Any help would be appreciated with work shown (including units).Thank you in advance!
1.) Iron has a body-centered cubic unit cell, and a density of 7.87 g/cm3. Calculate the edge length of the unit cell, in pm. (The atomic mass of iron is 55.85 amu. Also, 1 amu = 1.661 × 10-24g.)
2.) CsCl crystallizes with a body centered cube unit cell. 1 Cs atom in center of cube and surrounded by Cl- anions in corners ( rCl = 181 pm) : Edge 412 pm calculate the radius Cs
