Answer:
0.154 M
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 = ? M
V₁ = 25.0mL
M₂ = 0.10 M
V₂ = 38.52 mL
Using the above formula , the molarity of acid , can be calculated as ,
M₁V₁ = M₂V₂
Putting the respective values ,
M₁ * 25.0mL = 0.10 M * 38.52 mL
M₁ = 0.154 M
