Answer:
V₂ = 134.32 mL
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = 1.50 M
V₁ = 67.7 mL
M₂ = 0.756 M
V₂ = ?
Using the above formula , the volume of base , potassium hydroxide , can be calculated as ,
M₁V₁ = M₂V₂
1.50 M * 67.7 mL = 0.756 M * V₂
V₂ = 134.32 mL
