Two molecules, A and B, interconvert to form an equilibrium solution. You start with an initial concentration of 100 micromolar of A and 0 micromolar B. At time teq, an equilibrium is reached with concentration of A and B as [A] and [B]. The molar absorptivity at 500 nm is 5800 M-1 cm-1 for A and 2010 M-1 cm-1 f

Question

Two molecules, A and B, interconvert to form an equilibrium solution. You start with an initial concentration of 100 micromolar of A and 0 micromolar B. At time teq, an equilibrium is reached with concentration of A and B as [A] and [B]. The molar absorptivity at 500 nm is 5800 M-1 cm-1 for A and 2010 M-1 cm-1 for B. At time teq, you measure the absorbance at 500 nm to be Abs = 0.45; you use a cell with pathlength 1.0 cm.

1. What is [A] in units micromolar? Report your answer to the ones place (no decimal places). 

2. For the problem above, what is [B] in units micromolar? Report your answer to the ones place (no decimal places)
