Hey whats the question? I just did this the other day but what do you want the answer for like how?
Answer:
The answer to your question is the second option: 2M NaOH solution
Explanation:
Data
Volume 1 = 0.5 l
Concentration 1 = 12 M NaOH
Volume 2 = 3 l
Concentration 2 = ?
Formula
V₁C₁ = V₂C₂
Solve for C₂
C₂ = V₁C₁ / V₂
Substitution
C₂ = (0.5)(12) / 3
Simplification and result
C₂ = 6 / 3
C₂ = 2 M
Answer: 800 mL of methyl alcohol should be added to 200 ml of water to make this solution.
Explanation:
Volume of the methyl alcohol = x
Volume of water = y = 200 mL
Volume of the solution ,V = x + y
Volume percentage of solution = 80%
x = 800 mL
800 mL of methyl alcohol should be added to 200 ml of water to make this solution.
