Question

Calculate the concentration of the lycopene solution in the spectrophotometer

Answer 1

(a) Calculate the concentration of the lycopene solution in the spectropholometer cell before isomerization, given that the molar absorptivity of lycopene at 471 nm is 1.86 × 104. (b) Calculate the mass of lycopene in 3.0 mL of the solution that has the concentration you calculated in (a).

Step-by-Step Solution:

Step 1 of 4

Lambert and beers has given equation which is represented as follows:



Where,

Absorbance

is the molar absorbance

is the cell path length

Concentration of sample

Here we have molar absorption that is, path length is 1cm so after getting absorbance we can calculate concentration of lycopene in medium. This concentration will be in gm/100mL.
