how many grams of Na2SO4 can be produced by the reaction of 250g of NaOH with sufficient H2SO4?

1 answer

2NaOH + H2SO4 ==> Na2SO4 + 2H2O

mols NaOH = grams/molar mass
Convert mols NaOH to mols Na2SO4 using the coefficients in the balanced equation.
Now convert mols Na2SO4 to g. grams = mol x molar mass.
