AI Generated Solution

To find the ratio of the unit cube edges of KCl and NaCl, we can follow these steps: ### Step 1: Understand the relationship between molar volume and unit cell edge length The molar volume (V_m) of a substance is related to the volume of its unit cell (V_cell) and the number of formula units per unit cell (Z). The formula is given by: \[ V_m = \frac{V_{cell}}{Z} \] ...
