The entire process, assuming their degrees of ionization to be 1 due to their strong acid/base properties, should be

2NaOH + H2SO4 - - > 2H2O + Na2SO4

Therefore, if 200 grams of sodium hydroxide are used with molar mass 40, than 5 mols of sodium hydroxide was used. Using the ratio of 2:1:2:1, we see that 2.5 mols of Na2SO4 was used, therefore 2.5*molar mass = 2.5*142 = 355 grams.
