Question

If you have an equation for a line, y = 0.15x + 0.010, where y is absorbance and x is concentration in molarity of Fe (2+), calculate the concentration of a test sample with an absorbance of 0.065.

What is the absorbance value for the blank in this experiment?

Answer 1

.065 = .15 x + .01

.15 x = .055

x = 5.5/15
