50% by weight NaOH = 50 g NaOH/ 100 g solution

Normality = grams/liter

50 g/liter = 50 g/1000 g soln = 0.5 N

Let 50% NaOH solution be called S. Density = 1.530gNaOH/mL. Atomic weights: Na=23 O=16 H=1 NaOH=40

50gNaOH/100gS x 1molNaOH/40gNaOH x 1.530gS/1mLS x 1000mLS/1LS = 19 molNaOH/L = 19N

I give only two significant figures, because 50% was only given with two.
