Use the data given below to construct a Born - Haber cycle to determine the electron affinity of Br?

DH°(kJ)

K(s) → K(g) 89

K(g) → K⁺(g) + e⁻ 419

Br2(l) → 2 Br(g) 193

K(s) + 1/2 Br2(g) → KBr (s) -394

KBr(s) → K⁺(g) + Br⁻(g) 674

I know the answer is -325 kj, I want to know how to get it. Thanks
