2. A calibration curve for FD   C Blue #1 was found to be A = 105,689(L)/(mol·cm)[B1] - 0.004.5.00ml of solution containing an unknown concentration of FD   C Blue #1 was diluted to25.00ml. The absorbance of the diluted unknown solution was 0.378 using a 1.00cmcuvette. What is the concentration of FD   C Blue #1 in the original, undiluted sample?[B1]unk = 1.89 × 10^-7(mol)/(L)
