Answer:
volume is 32.00 mL
Explanation:
the balanced equation for the neutralisation reaction is as follows
2NaOH + H₂SO₄ ---> Na₂SO₄ + 2H₂O
molar ratio of NaOH to H₂SO₄ is 2:1
number of H₂SO₄ moles reacted - 0.4000 mol/L x 10.00 x 10⁻³ L = 0.00400 mol
according to the molar ratio
number of NaOH moles reacted - 2 x number of H₂SO₄ moles reacted
number of NaOH moles reacted - 2 x 0.004000 mol = 0.008000 mol
concentration of NaOH is - 0.2500 mol/L
concentration = number of moles of solute / volume
rearrange the equation
volume = number of moles / concentration
volume = 0.008000 mol / 0.2500 mol/L
volume = 0.03200 L
therefore volume is 32.00 mL
