This balanced equation shows the reaction of sodium hydroxide and sulfuric acid:
2NaOH + H2SO4 → Na2SO4 + 2H2O.
In a laboratory experiment, a student mixes 355 grams of sulfuric acid with an excess of sodium hydroxide. What is the theoretical mass of sodium sulfate produced? Refer to the periodic table and the polyatomic ion resource.

Answer:
514.04 grams
Explanation:
since the no of moles of H2SO4= no of moles of Na2SO4;
no of moles of H2SO4=355/98=3.62 moles----(1)
Mass of Na2SO4 therefore produced= 142(no of moles)----(2)
From 1 and 2 ; mass of na2so4=514.04gms
