Answer #1

Suppose Y-axis represents the absorbance of known compound and X-axis represents the concentration of the known compound.

Now take the unknown sample and find out the absorbance using photometer and then see the respective concentration that is the concentration of your unknown solution.

For example, suppose the absorbance of unknown compound come to 0.811 so the corresponding concentration from the graph is 4 and hence 4 is the concentration of the unknown solution.

How do I find the weight precent iron (II)? We measured 1.0014 g of unknown iron sample and added 100.0 mL water. Then pipetted 10.00 mL of the first solution into a beaker and added 90.00 mL of water. Then added 1,000 microliters of the second solution to a plastic container along with the reagents needed to analyze it with a spectrophotmeter. This solutions total volume was 10.00 mL. I then measured the absorbance of this solution and got .019...

During the spectrophotometric analysis of an unknown, the absorbance of a solution of unknown concentration is measured, and the value is higher than the highest standard used to make the standard curve. What should be done to make sure that the standard curve can be used to determine the concentration of the unknown? A) Dilute the unknown so that it will have an absorbance within the standard curve. Once the diluted unknown concentration is determined, the full strength concentration can...
