how many grams of NaOH are needed to react with two moles of H2SO4
Answered by DrBob222
2NaOH + H2SO4 ==> Na2SO4 + 2H2O

1 mol H2SO4 needs 2 mols NaOH; therefore, 2 mol H2SO4 will need 4 mols NaOH. Then grams = mols x molar mass
Answered by erika
so grams = 4 * 39.98 ? = 159.92

Ignoring significant figures, yes.
