1 of 4 Watch the video that shows using the dilution method to make a solution of known concentration. Note that while the video shows the use of a beaker, in the lab we typically use a volumetric flask to make the diluted solution. The stock solution of KMnO, has a concentration of 2.6 10-4 M. The pipette has a volume of 10.0 mL. What is the amount of KMnO, delivered to the solution, in moles? mol X resubmit

1.A student delivered 11.85 mL (V1) of 2.49 % stock solution (M1) using a graduated pipette into a 50.00 mL (V2) volumetric flask. Distilled water was added to the flask to the graduation mark and mixed well. Using the dilution equation (provided below), calculate the concentration of the diluted solution. (M1)(V1) = (M2)(V2) Report your answer to 3 decimal places. 2.Density is given by the equation density=mass/vol (d=m/V). Given that the density of magnesium is known to be 1.74 g/mL,...

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...

Dilution is a process in which the concentration of a solution is lowered by adding more solvent. Some of the reasons dilutions are performed are to minimize measurement errors when preparing a series of solutions at different concentrations, to save time and laboratory space, and to make more accurate measurements on an analytical balance when the target concentration is very low. The new concentration of a diluted solution can be determined from the following equation, sometimes called the dilution equation,...
