Consider the strong electrolytes ZₘXₙ, UₘYₚ and VₘXₙ. Limiting molar conductivity (Λ⁰) of UₘYₚ and VₘXₙ are 250 and 440 S cm² mol⁻¹, respectively. The value of (m + n + p) is _______. Given: λ⁰(Zⁿ⁺)=50.0, λ⁰(Uᵖ⁺)=25.0, λ⁰(Vⁿ⁺)=100.0, λ⁰(Xᵐ⁻)=80.0 and λ⁰(Yᵐ⁻)=100.0 S cm² mol⁻¹. λ⁰ is the limiting molar conductivity of ions. The plot of molar conductivity (Λ) of ZₘXₙ vs c¹ᐟ² is given below.
