Answer:
600 mL
Explanation:
The volume of 10% acid solution used to make the mixture = 200 L
Let the volume of 30% acid solution used to make the mixture = x mL
Total volume of the mixture = (200+ x) mL
For 10% acid solution:
C₁ = 10% , V₁ = 200 mL
For 30% acid solution :
C₂ = 30% , V₂ = x mL
For the resultant solution of sulfuric acid:
C₃ = 25% , V₃ = (200 + x) mL
Using
C₁V₁ + C₂V₂ = C₃V₃
10×200 + 30×x = 25×(200 + x)
Solving for x,
x = 600 mL
<u>600 milliliters of solution Y must be added to 200 milliliters of solution X to create a solution that is 25 percent alcohol by volume.</u>

Answer:
Number of mole in H2O = 5.4 moles
Explanation:
Given:
Mass of H2O = 97.3 gram
Find:
Number of mole in H2O
Computation:
We know that molar mass of H2O = 18 g/mole
So,
Number of mole = Given Mass / Molar mass
Number of mole in H2O = Mass of H2O / Molar mass of H2O
Number of mole in H2O = 97.3 / 18
Number of mole in H2O = 5.4055
Number of mole in H2O = 5.4 moles
Answer:
Electrons in a hydrogen atom must be in one of the allowed energy levels. If an electron is in the first energy level, it must have exactly -13.6 eV of energy.
...
Energy Levels of Electrons.
Energy Level Energy
1 -13.6 eV
2 -3.4 eV
3 -1.51 eV
4 -.85 eV
The correct mole ratio of K₃PO₃ and KNO₂ in the chemical reaction is 1 : 3
<h3>Balanced equation</h3>
3Mg(NO₂)₂ (aq) + 2K₃PO₃ (aq) -> Mg₃(PO₃)₂(aq) + 6KNO₂(aq)
from the balance equation,
- The number of mole of K₃PO₃ = 2 moles
- The number of mole of KNO₂ = 6 moles
<h3>How to determine the mole ratio of K₃PO₃ and KNO₂</h3>
- Number of mole of K₃PO₃ = 2 moles
- Number of mole of KNO₂ = 6 moles
- Mole ratio of K₃PO₃ and KNO₂ =?
Mole ratio = mole of K₃PO₃ / mole of KNO₂
Mole ratio of K₃PO₃ and KNO₂ = 2 / 6
Mole ratio of K₃PO₃ and KNO₂ = 1 : 3
