I need help solving this

Question

What volume of 500.0 mM drink mix would be needed to prepare 100.0 mL of a solution with an absorbance of 0.400

Answer 1

We can't answer this without additional information. We would need at a minimum to know the extinction coefficient of the drink mix. You would use Beer Lambert law where A = ecl

A = absorbance

e = extinction coefficient

c = concentration (M)

l = path length
