5. A solution prepared by mixing 10.00 mL of unknown (X) with 5.00 mL of standard (S) containing 8.24 ug S/mL, and diluting to 50.0 mL. The measured signal quotient was (signal due to X/signal due to S) = 1.90/1.000. In a separate experiment it was found that, for equal concentrations of X and S, the signal quotient was (signal due to X/signal due to S) = 0.930/1.000. Find the concentration of X in the unknown. а. b. Answer the same question if in a separate experiment it was found that for the concentration of X equal to 3.42 times the concentration of S, the signal quotient was (signal due to X/signal due to S) = 0.930/1.000.

Please show all the calculations with steps and explanations

Define the following terms: spectrophotometer, absorbance, pathlength, & (also known as molar absorptivity), concentration, transmittance, Beer's law. RODUCTION:

A 0.0140 M solution of a certain analyte exhibits 49.8% T' at a wavelength of 280 nm. What will the percent transmittance be for a 0.0252 M solution of the same analyte? Assume the pathlengths for each measurement are equal.
