A student creates a sports drink by dissolving 5.0 g of powder in 250 mL of water. The green colour of the drink is due to the presence Green Dye X, which has a lambdamax of 630 nm. A calibration curve (absorbance versus concentration) at lambdamax is created for varying concentrations (mM) of Green Dye X which has the equation y = 26.8x. If 1.0 mL of the sports drink is diluted to 10. mL with water, then the absorbance is measured to be 0.340, what is the mass percent of Green Dye X in the drink powder if the molecular weight is 418.4 g mol-1?

What is the wavelength in nm of 7.47*10-19

Logically deduce the structure of compound 1B whose Spectra are given: Molecular formula C4H8O

Topic: Transmittance and absorbance, lambert-beer law Ketorolac Tromethamine (C15H13NO3 • C4H11NO3) has an absorbance of 0.615 at 318.6 nm and 1 cm optical path in 3.5 µg / mL concentration solutions. A 2.9252 g sample from a tablet is diluted with water to 250 mL. They take 25 mL add 3.0 mL of 0.1 N H2SO4 and dilute to 500 mL. A 10 mL aliquot is taken and diluted to 200 mL. Of the latter solution, the absorbance at 318.6 nm is measured, resulting in 0.523. Calculate the milligrams of Ketorolac Tromethamine for each compressed. Fact: Average weight of 6 tablets equals 1924.5 mg
