Find the position of the absorption peak of a low-resolution spectrum of ¹2C¹80

Here is an energy level diagram that illustrates the absorption process. Energy ES (n=5) E4 (n=4) E3 (n=3) E2 (n=2) E1 (n=1)

In a mass spectrometer, two beams of singly ionized isotopes of uranium 23592U and 23892U are injected with velocity 1.4*105m/s into a magnetic field of strength 0.7 T normally. Compute the distance d between the two trace lines of the isotopes after they complete one semi-circle. (Given: masses of the isotopes are m235 = 3.9*10-25 kg and m238 = 3.95*10-25) a) 1.26 cm b) 0.63 cm                       c) 0.32 cm                       d) none of these.

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 = 26.4x. If 1.0 mL of the sports drink is diluted to 10. mL with water, then the absorbance is measured to be 0.450, what is the mass percent of Green Dye X in the drink powder if the molecular weight is 418.4 g mol-1?
