please do #2 question but if you want to check my #1 please do lol. Thanks !!

1) For each of the following pairs of wavelengths below, circle the one that is higher in energy. A wavelength in the IR region or a wavelength of 1nm 280nm of 340nm 280nm pr a wavelength that produces green light 490570nm 2) In the lab you have a solution of compound Y and you know that the molar absorption coefficient at 504nm is 1.2103M1cm1. You take the absorbance at 504nm and the absorbance is 2.200, which is outside the linear range of the instrument, so you dilute the sample thus: 300L of sample is added to 2.700mL of water. After mixing the diluted sample you retake the absorption at 504nm and the instrument now reads 0.583. Calculate the concentration of the undiluted, original sample. Show all your work below
