Silver(1) oxide (Ag2O), forms a cubic unit cell structure as shown in Figure 2. i. How many Ag and O2 ions are there in the unit cell? Explain how you

arrived at your answers. ii. How many formula units are there in the unit cell? iii. What is the coordination number and geometry around each oxygen ion? b. (8 marks) The unit cell of Ag,0 has length a = b = c = 472 pm. Calculate the density of silver oxide and give your answer in both g cm3 and kg m. (Use the relative atomic mass of Ag as 107.9 and O as 16.0 in your calculation and show all your working.)
