What is the molarabsorptivity? What is the concentration of a copper dithizone solution that transmits 20 % under thesame conditions?2.Virtual Lab Question: Phosphorus in urine can be determined by treating with molybdenum (VI) andthen reducing the phosphomolybdo complex with aminonaphtholsulfonic acid to give thecharacteristic molybdenum blue color. This absorbs at 690 nm. A patient excreted 1270 mL of urinein 24 hours and the pH of the urine was 6.5. A 1.00 mL aliquot of the urine was treated withmolybdate reagent and aminonaphtholsulfonic acid and was diluted to a volume of 50.0 mL.A series of phosphate standards were similarly treated. The absorbance of the solutions at 690 nm.measured against a blank, were as follows:SolutionAbsorbancea. Calculate the number of grams of phosphorusexcreted per day.1.00 ppm P0.205b. Calculate the phosphorus concentration in the urine2.00 ppm P0.41as millimoles per liter.3.00 ppm P0.6153.Virtual Lab Questionsa. Compare the magnetic character, bond lengths,4.00 ppm P0.82bond orders, bond dissociation energies, andUrine sample0.625relative ionization energies for N2, N2", and N2",using the Molecular Orbital Theory.b. For the molecule selenium tetrafluoride, SeF4, provide a Lewis structure and the hybridizationof the central atom. Sketch the species, showing all bond types (identical to that shown inlectures, such as o(1s, sp3)) and bond angles. Name the geometry about the central atom.9(D) - 7
