Sample Exercise 12.1 Calculating Packing Efficiency
www.centrallyon.orgmost solids fall between the density of lithium (0.5 g/cm 3) and that of iridium (22.6 g/cm ), so this value is reasonable. Practice Exercise Estimate the length of the cubic unit cell edge and the density of CsCl (Figure 12.26) from the ionic radii of cesium, 1.81 Å, and chloride, 1.67 Å. Answer: a = 4.02 Å and ρ= 4.31 g/cm3
Sample Exercise 15.1 Writing Equilibrium-Constant Expressions

Solve With 2 mol of gaseous products (2 NH 3) and 4 mol of gaseous reactants, (1 N 2 + 3 H 2), n = 2 –4 =2. (Remember that functions are always based on products minus reactants.) The temperature is 273 + 300 = 573 K.
