Let it dry. Repeat step 1-2 for other 3trials with different developing solvents.3.Fill each of four 50ml graduated cylinders with four different solvents you choose to about 5 ml. Use a corkstopper to suspend each filter paper strip in a graduated cylinder, as shown in Figure 4.1. The end of the filterpaper should be below the solvent level; the dye spot should be above the solvent level.Permit the solvent in each graduated cylinder to rise up the filter paper until it is about 2cm from the top of4.partices, (atoms or TonstRemove the strips from the graduated cylinders.

Patients undergoing an upper gastrointestinal tract laboratory test are typically given an X-ray contrast agent that aids with the radiologic imaging of the anatomy. One such contrast agent is sodium diatrizoate, a nonvolatile water-soluble compound. A 0.378-m solution is prepared by dissolving 38.4 g sodium diatrizoate (NaDTZ) in.l.60 102 mL water at 3 1.2C (the density of water at 31.2C is 0.995 g/cm3). What is the molar mass of sodium diatrizoate? What is the vapor pressure of this solution if the vapor pressure of pure water at 31.2C is 34.1 torr?

Which is correct? Random errors affect accuracy and systematic errors affect precision. An accurate result shows agreement with the true or accepted value. Precise results can contain significant random error, but little systematic error. The standard deviation is a good measure of accuracy. Polydimethylsiloxane (PDMS) stationary phases have low polarities. Which of the following statements is TRUE about gas chromatography using PDMS stationary phases? The gas chromatography column is typically packed with silica microparticles. An oven is used to control the column temperature because a constant temperature is always needed in gas chromatography Octane (C8H18, boiling point: 126 ºC) is eluted later than dodecane (C12H26, boiling point: 216 ºC) 3-Pentanone ((C2H5)2CO, boiling point: 102 ºC) is eluted later than propanol (CH3CH2CH2OH, boiling point: 97 ºC)
