5070The mole and the Avogadro constant
In a titration, a 25.0 cm³ sample of 0.100 mol / dm³ sodium hydroxide is exactly neutralised by 16.2 cm³ of dilute sulfuric acid. The equation for the reaction is shown. H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O What is the concentration of the dilute sulfuric acid?
- A0.0648 mol / dm³
- B0.0772 mol / dm³
- C0.154 mol / dm³
- D0.309 mol / dm³
