How many moles of H2SO4 are required to react with 50 mL of NaOH solution? NaOH is 1M.
2NaOH + H2SO4 ==> Na2SO4 + 2H2O
How many mols H2SO4 do you have? That's mols H2SO4 = M x L = 1M x 0.050L = ?
From the equation you know that 2 mols NaOH are needed for 1 mol H2SO4; therefore, 2*0.050 = mols NaOH needed.
