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 ;
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%
