Answer is: volume of sodium hydroxide is 500 cm³.
Chemical reaction: H₂S + 2NaOH → Na₂S + 2H₂O.
From chemical reaction: n(H₂S) : n(NaOH) = 1 : 2.
n(NaOH) = 2 ·0.050 mol.
n(NaOH) = 0.1 mol.
V(NaOH) = n(NaOH) ÷ c(NaOH).
V(NaOH) = 0.1 mol ÷ 0.2 mol/dm³.
V(NaOH) = 0.5 dm³.
V(NaOH) = 0.5 dm³ · 1000 cm³/dm³.
V(NaOH) = 500 cm³.
