Question 1 Referring to Table 1 on page 9, what is the final concentration of Fe+2 in ppm of the last standard solution assuming that you used exactly the target value of 8.00 ml Fe+2 in the 100 mL flask? For this question, assume that you added exactly the volumes of all reagents as listed in the table. (Remember that the stock solution concentration is 50.00 ppm.) Show all your work carefully using good form and significant figures. Table 1: Components...

I am stuck on how to find concentration for standards and unknowns. Any kind of help would be appreciated. The corrected absorbance is = Blank - absorbance 1. Prepare the BCA working reagent. Use a graduated cylinder and add 30 ml of the BCA reagent into a 50 ml Erlenmeyer flask. Use the appropriate micropipette to add 600 uL of the CuSO4 solution into the flask and mix by swirling the flask. Record the exact mass of albumin and the...
please show work so: 1 ml stock 10 ml final -0.5 mL of stock -5 ml final volume While I have used 1:10 as a standard the same rules apply for all dilution factors. Try these problems: x 0.5 X0.5 1. You need to make a 1:25 dilution factor. If you final volume is 25 mL this means that you need_ _mL of stock and mL of solvent to make your final volume of 25 mL. 2. If you needed...

For all calculations, show all work and draw a box around the final answers. 1. Does the solubility of all solids in water increase with temperature? If not, list any exceptions shown in Figure 1 (do not include gases). 2. A 0.0500 M solution had an absorbance of 0.399. An unknown solution of the same solute in the same spectrometer had an absorbance of 0.231. Calculate the second solution's concentration, in molarity (Hint: recall that e and I are constant)....
