Beer-lambert law of absorption.

  1. Dec 28, 2012 #1
    An aqueous solution of yeast nucleic acid of length 2.0*10^-2m and concerntrated 2.0mol m-3 has an absorptivity of 25m2 mol-1 at a certain wavelenght. calculate the percentages tranmission at this wavelenght.

    this is an example that i dont understant, please help me to simplify it and explain it more for me. you can send me as many example as possible.

    thank you for your kind attention.

    You can multiply concentration and absorptivity to get the absorption per length. This can be used in the Beer-Lambert law.
