Suppose you measure the absorbance of a yellow dye solution in a 1.00 cm cuvette. the absorbance of the solution at 427 nm is 0.20. if the molar absorptivity of yellow dye at 427 nm is 27400 m–1cm–1, what is the concentration of the solution?

The concentration of the yellow dye solution as obtained is 7.29 × 10-⁶M.

BEER-LAMBERT EQUATION:

A = εbc

Where;

c = A ÷ εb

c = A ÷ εb

c = 0.20 ÷ (27400 × 1)

c = 0.20 ÷ 27400

c = 7.29 × 10-⁶M

Therefore, the concentration of the yellow dye solution as obtained is 7.29 × 10-⁶M.

what does the table look like

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
