step1:- to calculate moles of each.
mole of NaOCl = 0.524 L x0.161 mol/L = 0.08436 moles
moles of HOCl = 0.132 L x 0.381 mol/L = 0.0503 moles
step2:- to calculate molarity in total volume
total volume = 0.524+0.132 =0.656 L
[NaOCl] = 0.08436/0.656 = 0.1286 M
[HOCl] = 0.0503/0.656 = 0.07668 M
step3:- to calculate pH
pH = pKa + log{[OCl-]/[HOCl]}
= -log(3.2x10-8) + log(0.1286/0.07668)
= 7.72
