Consider an Ionic Compound C_xA_y Where the Anions (A) Are

question 70

Short Answer

Consider an ionic compound C_xA_y where the anions (A) are in a body-centered cubic arrangement and the cations (C) are located in all of the faces of the cubic unit cell.
A. What is the empirical formula of the salt?
B. If the edge length of the unit cell is 5.00 × 10 cm and the molar masses of C and A are 50.0 g/mol and 100.0 g/mol, respectively, calculate the density of C_xA_y.
C. If the ionic radius of A is 200. pm, estimate the ionic radius of C.
