How to Use a Volumetric Flask in the Chemistry Lab

SOLVED: A student pipetted 25.00 mL of a stock solution that was 0.1086 M HCl into a 100.00 mL volumetric flask and diluted the solution to the volumetric flask calibration mark with deionized water. Calculate the concentration (M) of the diluted solution. Do not include units in your typed answer. Type answer:

SOLVED:Which of the following does NOT require calibration in the clinical laboratory? a. Electronic balance b. Liquid in glass thermometer c. Centrifuge d. Volumetric flask e. Air displacement pipet

The amount of caffeine in an analgesic tablet was determined by HPLC using a normal calibration curve. Standard solutions of caffeine were prepared and analyzed using a 10-μL fixed-volume injection loop. Results for the standards are summarized in the following table. concentration (ppm) signal (arb. units) 50.0 8354 100.0 16925 150.0 25218 200.0 33584 250.0 42002 The sample is prepared by placing a single analgesic tablet in a small beaker and adding 10  mL of met
