Question

Calculate the volume of unit cell if an element having molar mass 56 g mol − 1 that forms bcc unit cells. [ ρ . N A ​ = 4 : 8 × 1 0 24 g cm − 3 mol − 1 ]

TestHub · Accepted Answer

​ Density of unit cell = ρ = a 3 N A ​ M n ​ Volume of unit cell ( a 3 ) = ρ N A ​ M n ​ = 4.8 × 1 0 24 g cm − 3 mol − 1 56 g mol − 1 × 2 ​ = 2.33 × 1 0 − 23 cm 3 ​
