What do you need help with
Answer:
37.5 mL
Explanation:
To solve this problem we can use the formula:
C₁ = 0.400 M
V₁ = ?
C₂ = 0.150 M
V₂ = 100 mL
So now we <em>solve for V₁</em>:
- 0.400 M * V₁ = 0.150 M * 100 mL
So we need 37.5 mL of 0.400 M CuSO₄(aq) to make 100 mL of 0.150 M CuSO₄(aq). That volume could be measured in the 50 mL buret.
