[Single-digit Integer] The density of crystalline sodium chloride is 2.167 g/cm3. What would be the — Solid State Chemistry Question

💡 Solution & Explanation

Molar mass of $NaCl$ = 58.5 g/mol. Mass of 1 mole of $NaCl$ = 58.5 g. Volume of 1 mole of $NaCl$ = Mass / Density = 58.5 g / 2.167 g/cm3 = 27.0 cm3. Since the volume of a cube is V = L^3, the side length of the cube containing 1 mole is: L = (27.0)^(1/3) = 3 cm.
