Product description
68. The optical density of the furatsilin solution in the analyzed solution measured on the KFK-2 photoelectrocolorimeter with a certain light filter was 0.32, and the optical density of the standard furatsilin solution with a concentration of 0.010 mg / ml was 0.56. According to the table, plot the light absorption curve in the coordinates A=f(λ) and determine the light filter selected for this definition:
N filter
(λ, nm) 1(315) 2(364) 3(400) 4(440) 5(490) 6(540) 7(590) 8(670) 9(750)
A 0.1 0.17 0.25 0.56 0.30 0.24 0.18 0.11 0.06
Calculate the mass of furacilin in 50.0 ml of the analyzed solution.
