1. A stock solution of blue dye has a concentration of 4.0 x 10 M. If 8.00 mL water is added to 2.00 mL of the blue dye stock solution, what is the concentration of the new solution?
(16) Suppose you have a stock solution with a solute concentration of 150 mm. If you wanted to dilute this solution to make a total of 50 ml of a 25 mM solution, what volume of stock __and what volume of water_ would you use? Give your answer in ml, and show your calculations.

The concentration of dye in Solution A is 20.286 M. You have 13 mL of water at your disposal to make the dilutions. The solution is diluted twice, to make Solutions B and C. In the first dilution, 5 parts of Solution A is diluted with 12 parts water to make Solution B. In the second dilution, 2 parts of Solution B is diluted with 4 parts water to make Solution C. What is the concentration of dye in Solution...

Starting with a stock solution of 4 mM KMnO4, you plan to make 16 mL of each of the following concentrations of KMnO4: 1.0 mM, 250 μM, 62.5 μM , and 15.6 μM. What is the V1, expressed in mL, for this dilution series? Report your answer to 2 decimal places.
Question 4 2 pts During this week's experiment, a student was provided with a stock solution of FD&C Red 40 dye that was 0.381 mM. Following the procedure in the lab manual, she created Solution #2 by pipetting 19 mL of Solution #1 to a 25 mL volumetric flask, then diluted to the calibration line with Dl water. What is the concentration of Solution #2 in mM? Note: The units of mM are used for grading purposes, and are not...
A stock solution of bradford protein assay reagent contains 0.5 mg/ml or the reactive dye called brilliant blue G-250. to use the stock, you must first dilute it five-fold, i.e..,1/5X. what is the concentration of dye in the diluted working solution.
please hlep me answer those three questions asap.
Please ignore question 7.
Question 7 Working with buffers You need 100 ml of 120 mM phosphate buffer and you have two stock solutions from which you can make the buffer; 0.6 M NaH2PO4 (the acid form) and 0.6 M Na2HP04 (the base form). You need to add 3 times more of the base form than the acid form to achieve the desired pH. How will you make this solution? Question 8...
4) You have a 50 mM stock solution of sodium dodecylsulfate and you need to make 50 mL of a 0.1 mM solution. How much sodium dodecylsulfate will you need from the stock solution? 5) For Question #4, how much water will you need to add?
