You have 659.3 mL of a stock solution 4.660 M HCl. For a particular experiment, your lab partner prepared a diluted solution for you to use. In her notes, you read: " Using a volumetric pipet, took 246.54 mL of stock solution and diluted it to 739.21 ml in a volumetric flask. Then, took 100.00 mL of that solution and diluted it to 194.63 mL in a second volumetric flask. " What is the concentration that you should report for...

Suppose you have 100.00 mL of a solution of a dye and transfer 2.00 mL of the solution to a 100.00 mL volumetric flask. After adding water to the 100.00 mL mark, you take 5.00 mL of that solution and again dilute to 100.00 mL. If you find the dye concentration in the final diluted sample is 0.000129 M, what was the dye concentration in the original solution? Concentration

A student obtains 500.0 mL of a solution containing an unknown concentration of calcium iodide, CaI 2. She pipets 25 mL of this solution into a 100 mL volumetric flask and dilutes to the mark. She then pipets 10 mL of this diluted solution into a 50 mL volumetric flask and dilutes to the mark. She analyzes some of the solution from the final volumetric flask and finds that the iodide ion concentration is 0.0000064 M. Determine the molar concentration...

A 2.0 M stock solution of Tylenol was diluted as follows: 15.000 mL of stock solution was added to a 250-ml volumetric flask. Water was added to the flask until the solution's meniscus was at the line on the neck of the flask. 5.000 mL of solution from the 250-ml volumetric flask was added to a 100-ml volumetric flask. Water was added to the flask until the solution's meniscus was at the line on the neck of the flask. Calculate...
