Explanation 1) Concept: We use the concept of magnetic dipole moment. Using the equations, we find the number of atoms per unit volume, and then we can find the magnetic dipole moment. 2) Formulae: i) μ B = M m a x n ii) n = ρ N A M 3) Given: i) Saturation magnetization M m a x = 4.70 × 10 5 A / m ii) Density of nickel is ρ = 8.90 g / c m 3 iii) Molar mass of nickel is 58.71 g / m o l e 4) Calculations: First we find the number of atoms per unit volume. Using equation n = ρ N A M n = ( 8.90 ) ( 6.023 × 10 23 ) 58.71 n = 9.126 × 10 22 a t o m s c m 3 We can convert it in a t o m s / m 3 . We can write n = 9.126 × 10 22 a t o m s c m 3 × 1 c m 10 - 2 m 3 n = 9
