Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

Question

Using the mass spectrum, identify the hydrocarbon that will undergo combustion to generate carbon dioxide and water. What is the molecular formula for the hydrocarbon in the mass spectrum above?

Anionic surfactants in wastewater are measured spectrophotometrically as methylene blue active substances (MBAS). A volume of a water sample is first reacted with methylene blue, a cationic dye, in a basic buffered aqueous solution. The resulting solution is agitated after the addition of chloroform. The organic layer is then extracted, and the absorbance is read at 655 nm. A standard calibration curve is produced by plotting absorbance vs. concentration for the concentration range between 0 ppm to 2.50 ppm. The line had the following equation: y = 0.286x + 0.009 a. The limit of surfactant content in Philippine class B water is 300 ppb. If a 5 mL aliquot of a 50 mL water sample had an absorbance of 0.084 after MBAS analysis, is the sampled water body suitable for bathing? Support your answer

A student weighed out 0.150 g of protein powder and dissolved it in 100 mL of water (Solution 1). The student then diluted this solution by transferring 1 mL into a 25 mL flask and diluting with water (Solution 2). Finally, 1 mL of that solution was transferred to a test tube and combined with 4 mL Bradford reagent. The absorbance of the solution in the test tube was 0.144. Assuming that the best fit linear line of the standard curve was y=0.04144x+0.01521 (μgmL), calculate the percent protein by mass in the original protein powder.

In order to measure riboflavin in a breakfast cereal, a 5.00-gram sample of the cereal was extracted with acetic acid and filtered. The extract was transferred to a 50.0 mL volumetric flask and diluted to the mark. The sample was transferred to a cuvette and the fluorescence was measured. The instrument read 59 units (Fluorescence units –an arbitrary scale). 24.00 mL of the cereal extract was sample was mixed with 1.0 mL of a riboflavin standard that was 0.500 ug/mL. The fluorescence of this mixture was measured and read 94 fluorescence units. Calculate the concentration of riboflavin per gram of cereal (use µg/gram of cereal).
