What is the final concentration of a solution prepared by pipetting 10.00 mL of a 0.1284 M NaOH into a 25.00 mL volumetric flask and diluting with water to the mark?
A pipet is used to transfer 10.00 mL of a 4.00 M stock solution in flask “S” to a 25.00-mL volumetric flask “A,” which is then diluted with DI H2O to the calibration mark. The solution is thoroughly mixed. Next, 1.00 mL of the solution in volumetric flask “A” is transferred by pipet to a 50.00-mL volumetric flask “B” and then diluted with DI H2O to the calibration mark. Calculate the molarity of the solution in volumetric flask “B.”
a) Calculate the molarity of a solution of Erythrosin B, (FD&C Red #3) (MW 879.9 g/mol) if a 0.3500 g sample is diluted to 100 mL in a volumetric flask. You will be taking 5 ml of this solution and diluting to 100 ml in a volumetric flask. This will be solution 2. What is the molarity of solution 2? To make solution 3 you will take 5 ml of solution 2 and dilute it to 100 ml, what is...
Given this scenario: 1) If you dilute a solution by pipetting 10 mL of a pink solution into a 50 mL volumetric flask and you blow out the last drop from the pipet, then you dilute the solution until you reach the . 50 mL mark in the volumetric flask with water and mix it. The measured value for the absorbance should be _______ than the correct value? a) greater b) less c) equal to 2) If you prepare a...
A stock solution was prepared by dissolving 0.593 g of pure ASA (molar mass = 180.2 g/mol) with NaOH solution and diluting with water in a 1000 mL volumetric flask. This was followed by pipetting 4.00 mL of the stock solution into flask A and 5.0 mL of the stock into flask B. Flasks A and B were each diluted to 20 mL mark of the volumetric flask. What are the concentrations, in molarity, of ASA in flasks A and...

The molarity of a solution prepared by diluting 2.67 g of NaOH to 100.0 mL in a volumetric flask is?
A stock solution of Cu2+(aq) was prepared by placing 0.9157 g of solid Cu(NO3)2∙2.5 H2O in a 100.0-mL volumetric flask and diluting to the mark with water. A standard solution was then prepared by transferring 2.00 mL of the stock solution to a second 25.00-mL volumetric flask and diluting to the mark. What is the concentration (in M) of Cu2+(aq)in the stock solution? What is the concentration (in M) of Cu2+(aq)in the standard solution?
Start with a 1230.0 ppm Stock Zn solution. Prepare control 1 by diluting 2.00 mL of Stock Zn solution in a 200.0 mL volumetric flask and dilute to the mark. Prepare control 2 by diluting 2.00 mL of control 1 into a 100.0 mL volumetric flask. What is the Zn concentration (ppm Zn) in control 2? Report your answer to 4 decimal place.
