Question details

Hello, can anyone please help me with my lab reports. I did some calculation and found that the original concentration at zero is 1.4x10^-4M Based on the information below

You will be given a stock solution of the dye EVANS BLUE dissolved in distilled water whose concentration is 13.6 mg/dl (136 mg/liter) and whose molecular weight is 960.83. The absorbance of this solution is approximately 1.40 at 610 nm.

calculate final concentration of each dilution in mg/L and the molarity?

Tube mi of stock mi of water Molarity (mol/L) Absorbance(OD) Transmittion(%) 11.4 21 32.6 50.4 1.5 0.94 0.678 0.488 0.295 0.0

Thank you so much for your help!
