Question

You have two tubes that initially contain the same amount of starch. However, you add one microgram (1 ug) of amylase enzyme to Tube B and let it sit for 7 minutes. The resulting absorbances are 0.52 for Tube A and 0.26 for Tube B. What is the remaining starch concentration in Tube B? Enter only the numerical response (not the units) to one decimal place.

Answer 1

using beer-lambert law,

Abs =epsilon (c)( l)

epsilon and l and are constant

Abs1/c1=Abs2/c2
