Question

Which calculation is correct to determine the Conc. of Salicylic acid (M)?

1. (1.62M) (V1) = (100 mL)(M)

or

2. A= E L C

2. The salicylic acid - iron (IIl) complex absorbs maximally at 540 nm. Here is a set of data for solution percent transmittance at 540 nm as a function of salicylic acid concentration. To produce these data, samples of a 1.62 x 102 M solution of salicylic acid in water were added to a solution containing 2.00 mL of iron (Il) nitrate nonahydrate solution and distilled water in a total volume of 100.0 mL. Salicylic acid solution concentration 1.62 x 10 M Total volume 100.0 mL T at 540 nm 540 Vol, salicylic acid solution added 0.00 ml Conc. Salicylic acid (M) % T at 540 nm 95.0 % 46.1% 23.0 % 11.5% 1.4 % aa310, 1.00 mL 2.00 mL 3.00 mL 6.00 mL As you fil in the blanks in tha table above, please show one sample calculation of how you the concentration ofsalicylic acid in the assay mixtures and one sample calculation of
