Photons that are yellow have a wavelength of approximately [Select ] nm, and are higher in energy than [Select] photons and lower in energy than [ Select] photons.

1: Determine nominal m/z value peak 2: Assign the X+2 elements except oxygen (Br, Cl, Si, S) FIRST 3: Assign the X+1 elements (C & N) If N is known to be present, start with N remember to normalize X+1 to X, if necessary (when the X peak is not the base peak in the isotopic cluster) 4: Assign the atoms of oxygen after assigning number of C atoms because of the X+2 contribution from carbon6 can influence the assignment of the number of O atoms 5: Assign the X elements (hydrogen7 , F, P, I) 6: From the elemental composition, determine R+db 7: Propose a possible structure

A solution of a dye was analyzed by spectrophotometry, and the following calibration data were collected using a 1 cm cuvette. *graph in attachemnt*   Using the calibration data above for the dye solution, what is the dye concentration in a solution with an absorbance (A) = 0.52 if it was measured in a 1 cm cuvette?   Group of answer choices 3.0 x 10-6 M 6.0 x 104 M 2.0 x 10-6 M Not enough information is provided.

Please don't provide handwriting solution

With a resolution of 500 a peak will an m/z value of 297.000 from which of the following peaks?   297.439 297.603 297.356 298.000 297.232

I got 1.55 but it's not a choice so idk what to do
