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.
Here we have to calculate absorption.
Molecular weight of unknown compound = 160
Volume of ethanol = 10 mL
max = 247 nm.
The maximum absorption at 247 nm is 0.50(A)
Absorption of a molecule can be express as
A = Cl
Or, = A/Cl
If we express the mass into mole = 1mg =...
