Calculate the concentration (in%) if eugenol in oil of cloves based on Eugenol is 100%pure Absorbance Eugenol 0.9857 mass 0.01120g Oil of cloves Abs. 0.7856 mass 0.01105 Q. from orgaic chem. lab "Oil in Cloves"
Calculate the concentration (in%) if eugenol in oil of cloves based on Eugenol is 100%pure Absorbance Eugenol 0.9857 mass 0.01120g Oil of cloves Abs. 0.7856 mass 0.01105 Q. from orgaic chem. lab "Oil in Cloves"
Eugenol is 100%pure Absorbance Eugenol 0.9857 mass 0.01120g Oil of cloves Abs. 0.7856 mass 0.01105

Explanation / Answer

The absorbance of pure eugenol (0.0112 g) = 0.9857

The abosrobance of oil of cloves = 0.7856 (0.01105 g)

Absorbance 0.9857 due to 0.01120 grams

so 1 will be due to 0.0112 / 0.9857 grams

So 0.07856 absorbance will be due to = 0.0112 X 0.7856 / 0.9857 = 0.00893 grams

% of eugeneol = 0.00893 X 100 / 0.01105 = 80.81 %
