Problem 21P

One milligram of a compound of molecular weight 160 is dissolved in 10 mL of ethanol, and the solution is poured into a 1-cm UV cell. The UV spectrum is taken, and there is an absorption at . The maximum absorbance at 247 nm is 0.50. Calculate the value of for this absorption.

Step-by-Step Solution:
Step 1 of 3

Here we have to calculate absorption.

Step-1

Given:

l=1cm

Molecular weight of unknown compound = 160

Volume of ethanol = 10 mL

max = 247 nm.

The maximum absorption at 247 nm is 0.50(A)

Step-2

Explanation:

Absorption of a molecule can be express as

A = Cl

Or, = A/Cl

If we express the mass into mole =  1mg =...
