You are given the density of a metal as 3.03 g/cm³. You are advised the crystallographic structure is fcc, and the atomic mass is 28.1 g/mol. What is the atomic radius of the metal? O a. 0.14 nm O b. 0.10 nm O c. 0.11 nm O d. 0.16 nm

5- Question 5. Some hypothetical alloy is composed of 42.5 wt% of metal A and 57.5 wt% of metal B. If the densities of metals A and B are 4.35 and 6.27 g/cm3, respectively, whereas their respective atomic weights are 91.4 and 105.3 g/mol, determine whether the crystal structure for this alloy is simple cubic, face-centered cubic, or body-centered cubic. Assume a unit cell edge length of 0.395 nm.

I need help with the question in the picture below. the book refrenced is Materials Science and Engineering: An Introduction, 9e Thank you in advance
