Question: hello can anyone please help me with my lab reports...
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?
Thank you so much for your help!
