Answer:
0.1818 M
Explanation:
For the process of titration , the formula we use is -
M₁V₁ = M₂V₂
Where ,
M₁ = initial concentration of the acid
V₁ = initial volume of the acid
M₂ = final concentration of the base
V₂ = final volume of the base
Hence , from the question ,
The given data is ,
M₁ = ?
V₁ = 43.5 mL
M₂ = 0.0906 M
V₂ = 87.3 mL
Now, to determine the unknown quantity , the formula can be applied ,
Hence ,
M₁V₁ = M₂V₂
Putting the respective values ,
? * 43.5 mL = 0.0906 M * 87.3 mL
solving the above equation ,
M₁ = ? = 0.1818 M
