A= ε l c. (a) define the terms in the formula: a = ε l c. (pick your answers using the letter of the correct definition.)

a. pathlength of light through the cell
b. concentration, in mol/l, of the stock solution from which the sample was made
c. absorbance measured by the spectrometer
d. molar absorptivity, a constant unique to that substance at that wavelength
e. the wavelength of the light being used for the measurement
f. concentration, in mol/l, of the sample solution being measured definition of l definition of c definition of ε definition of a

Explanation:

Using Beer-Lambert's law :

Formula used :

where,

A = absorbance of solution

c = concentration of solution

l = length of the cell

= molar absorptivity of this solution

According to question:

A = (C) : absorbance measured by the spectrometer

c = (B) : concentration, in mol/L, of the stock solution from which the sample was made

l = (A): pathlength of light through the cell

ε =  (D) : molar absorptivity, a constant unique to that substance at that wavelength

step-by-step explanation:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
