Using the balanced equation, what is the concentration of H2SO4 solution?

Question

In a titration lab, a student finds that 0.0350 L of H₂SO₄ solution is needed to neutralize 0.0450 L of a 0.150 mol/L NaOH solution. Using the balanced equation, what is the concentration of the H₂SO₄ solution?

2 NaOH(aq) + H2SO4(aq) -> 2 H2O(l) + Na2SO4(aq)

Answer 1

2NaOH(aq) + H2SO4(aq) --> 2H2O(l) + Na2SO4(aq) ... balanced equation

moles NaOH used = 0.0450 L NaOH x 0.150 mol / L = 0.00675 moles NaOH

moles H2SO4 present = 0.00675 mols NaOH x 1 mol H2SO4 / 2 mols NaOH = 0.003375 mols H2SO4

Concentration of H2SO4 = 0.003375 mols H2SO4 / 0.0350 L = 0.0964 M
