Question

"In NaCl there are apprximately 106 Schottky pairs per
cm3 at room temperature In 1 cm3 there are
about 1022 ions Thus, there is one Schottky defect per
1016 ions " Please explain how it is
calculated that there is one Schottky defect per
101 6
ions

No of ions in 1 cm3 = 1022 ionsNo of Schottky defect per cm3 = 106 No of ions having one Schottky defect = Total number of ions in 1 cm3No of Schottky defect per cm3 = 1022106 = 1016That is there is one Schottky defect per 1016 ions

"In NaCl there are apprximately 106 Schottky pairs per cm3 at room temperature. In 1 cm3 there are about 1022 ions. Thus, there is one Schottky defect per 1016 ions." Please explain how it is calculated that there is one Schottky defect per 101 6 ions .

"In NaCl there are apprximately 10⁶ Schottky pairs per cm³ at room temperature. In 1 cm³ there are about 10²² ions. Thus, there is one Schottky defect per 10¹⁶ ions." Please explain how it is calculated that there is one Schottky defect per 10¹ ⁶ ions .
