You'll need to react 7,5 moles of Sodium with sulfuric acid to produce 3.75 moles of sodium sulfate
</span>
First of all, you need to balance the reaction. The balanced reaction is shown below (ensuring that the Law of Conservation of Mass is met on both sides):
2Na + H₂SO₄ → Na₂SO₄ + H₂
Now, all that you have to do is to use molar equivalences in this reaction applying the coefficients to calculate the moles of Sodium that you'll need:
Have a nice day!

Answer:
V₂ = 0.4 L
Explanation:
<u>Data:</u>
- P₁ (initial pressure) = 500 torr
- V₁ (initial volume) = 0.5 L
- P₂ (final pressure) = 700 torr
<u>Wanted:</u>
- V₂ (final volume)
<u>Equation:</u>
- P₁V₁ = P₂V₂ → V₂ = P₁V₁ / P₂
<u>Solution:</u>
- V₂ =
= 0.3571 L or 0.4 L
