The volume of the unknown solution obtained from the given standard curve is 2.57%
The linear equation produced by the standard curve is :
- y = absorbance ;
- x = concentration in percent (v/v)
Unknown Solution with absorbance value of 0.35 ;
- y = 0.35
Input the value of y into the equation.
Collect like terms
Divide both sides by 0.136
Hence, percentage by volume of the unknown solution will be 2.57%
