Answer:
The answer to your question is 30 ml of H₂SO₄
Explanation:
Data
the volume of H₂SO₄ = ?
[H₂SO₄] = 0.6 M
volume of NaOH = 90 ml
[NaOH] = 0.4
Process
1.- Write the balanced chemical equation
H₂SO₄ + 2NaOH ⇒ Na₂SO₄ + 2H₂O
2.- Calculate the moles of NaOH
Molarity = moles/volume
moles = Molarity x volume
-Substitution
moles = 0.4 x 0.09
-result
moles = 0.036 of NaOH
3.- Calculate the moles of H₂SO₄
1 mol of H₂SO₄ ---------------- 2 moles of NaOH
x ----------------- 0.036 moles of NaOH
x = (0.036 x 1)/2
x = 0.018 moles of H₂SO₄
4.- Calculate the volume of H₂SO₄
Volume = moles / Molarity
-Substitution
Volume = 0.018 / 0.6
-Result
Volume = 0.03 ml or 30 ml
