What is the molarity of the pesticide in the five ml flask

Reference no: EM13179780

A 20.0 mg sampele of a pesticide with a molecular mass = 385.91 was dissolved in a 5 mL volumetric flask. a 2.00 mL aliquot was withdrawn & placed in a 25 mL volumetric flask, and diluted to the mark.

what is the molarity of the pesticide in the 5 mL flask and in the 25 mL flask.

the 25 mL sample was placed in a 2.00 cm cuvet and you read an absorbance of 0.630 at 495 nm.

Calculate the molar absorbitivity (M-1 cm-1) at this wavelength.
