formule
L * K = A
K = A / L
K = 0.71cm⁻¹ * 6.0x10⁴
K = 1.26x10⁻⁴ Ω⁻¹cm⁻¹
^ = K / c = 4.26x10⁻⁴ * 1000cm³ / 0.001 mol dm⁻³
Λ = 426
Number of ion = 2
b) Predict how many ions would be produced per formula unit of the compound, tetraamminetrinitrocobalt(III),
assuming that it is monomeric and contains an octahedrally coordinated cobalt metal ion?
