2. The Anemovax COVID-19 vaccine uses 0.950% (w/v) NaCl (normal saline, preservative- free) as its diluent. After removing from the freezer or refrigerator, the vaccine must be mixed with the diluent before administration. It is diluted to a total volume of 10.0 mL, and each vial contains eight doses. a. Calculate the mass (in grams) of NaCl that is needed in order to prepare a total of 10,000 doses of the vaccine. b. Express the concentration of the vaccine diluent in molarity. (MW = 58.44 g/mol)

Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD50 value for humans is the same as for rats. Calculate the number of mg of Allura Red present in an 8 fluid ounce glass of the beverage you used in this lab. Assume that the concentration of Allura Red in the beverage is 0.000054 M. The molar mass of Allura Red is 496.42 grams/mol 1 fl oz = 29.5735 mL Do not include units with your answer.

Calculate the number of mg of Allura Red present in an 9 fluid ounce glass of the beverage you used in this lab and use this calculation to determine the number of such glasses of Allura Red sports drink required to reach the LD50 of 10,000 mg of Allura Red/kg body weight. Assume that the concentration of Allura Red in the beverage is 0.000038 M and the person has a body weight of 175 lbs.

Q25: There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiple the series of dilutions together to find the final dilution value. If 2 serial dilutions are performed, each with a value of 1, what is the cumulative dilution? Express your answer as standard notation with zero decimal places.

Mass of sample = 0.2492g Number of insects = 6 Initial watch glass weight = 90.7712g Weighing of watch glass after hexane evaporation = 90.8850g Mass of crude fats = 0.1138g Percent of crude fats in tissue sample = 45.67% 1.) For adults, the recommended daily intake of fats is around 60g. Based on the class results above, how many grams of the tissue analyzed would you have to consume to meet the daily requirement? 2.) How many insects would have to be consumed to meet the daily requirement? 3.) Butter is about 85% fat, and a typical person spreads about 3g of butter on a piece of toast. How many bugs would you have to spread on your toast for an equivalent amount of fat? 4.) The crude fat could also be converted to methylated fatty acids and used as a biofuel in diesel engines and aircraft. Note the mass of the biofuel is essentially the same as that of the crude fats used to make it. a) If the biofuel has a density of 880g/L, how many grams of insects would be needed to make a…
A student is recrystallizing 2.034 g of acetylsalicylic acid (aspirin) that was isolated from 8.00 grams of Excedrin. The recrystallization requires a seed crystal to begin. The seed crystal weighs 0.389 g. The student's actual yield after recrystallization is 1.663 g. What is the percent recovery?

1. A 100 mg vitamin C tablet weighted 0.645 g. A student crushed the tablet and transferred 0.119 g of the crushed powder into a 100 mL volumetric flask. What is the expected mass of ascorbic acid in the volumetric flask (in mg), according to the vitamin C manufacturer's label? 2. A 100 mg vitamin C tablet weighed 1.681 g. A student crushed the tablet and transferred 0.150 g of the crushed powder into a 100 mL volumetric flask, dissolved the powder in ~30 mL DI water, then filled the flask to the calibration line with DI water and mixed well to create Solution 1. The student then transferred 19.82 mL of Solution 1 into a 100 mL volumetric flask and diluted to the calibration line with DI water to create Solution 2. Calculate the expected concentration (in mM) of ascorbic acid in Solution 2. Hint: Remember that you are starting with a 100 mg vitamin C tablet.
