please provide the correct answer for questions 3 and 4.

When comparing your spectra, you should observe that the max of the standard and unknown solutions are almost the same. From this observation, which conclusions about the composition of the solutions are reasonable? (check all that apply) The other vitamins in the sample do not absorb light at that wavelength. The concentration of riboflavin in the two solutions is almost the same. The concentration of riboflavin in the standard is higher than the unknown. The concentration of riboflavin in the unknown is higher than the standard. The other vitamins in the sample absorb light at that wavelength. QUESTION 4 When comparing your spectra, you should observe that the maximum absorbance of the standard and unknown solutions are very different. From this observation, which conclusions about the composition of the solutions are reasonable?

The concentration of riboflavin in the unknown is higher than the standard. The other vitamins in the sample absorb light at that wavelength. The concentration of riboflavin in the standard is higher than the unknown
