Drug: C20H22ClN (Flexeril also known as iCyclobenzaprine HCl Using unit analysis, clearly show the set-ups for your calculations. You wish to prepare 50.0 mL of 2.30 x 10–2 M solution of your drug. (hint-how many grams will you need of your drug?) Describe how to prepare this solution from the pure drug and deionized water. Analytical balances and volumetric flasks are available to you. (Assume that your drug dissolves in water, at least to the extent necessary for this problem.) Use complete sentences in your description of the solution preparation process. A patient is given 2.0mL of a 3.00% (m/v) solution of your drug, how many milligrams of the drug did they receive? What is the molarity of a 3.00% (m/v) solution of your drug?
A student determines the molar mass of a liquid unknown by the method used in this experiment. She found that the equilibrum temperature of a mixture of ice and water was 1.0 degrees C on her thermometer. When she added 11.1 g of her unknown sample to the mixture, the temperature, after thorough stirring, fell to -3.0 degrees C. She then poured off the solution through a screen into a beaker. The mass of the solution was 90.4 g. Kf=1.86 degrees C/m How much water was in the decanted solution? What did she find to be the molar mass of the unknown liquid, assuming she made the calculation properly?

A student analysed mercury content on a canned tuna. According to EPA standard, the permissible limit of mercury in fish is 0.1 ppm. In this study, an average of 11.4 ± 2.1 ng/g was obtained based on six sample replicates. Suggest a suitable analytical instrument to be used in this analysis and draw a conclusion on the safety of mercury content of this canned tuna.
A standard solution mixture containing each element at 500 ppm is provided. You will need to carefully dilute this so that your total volume is up to 50ml per standard solution mixture in the digitubes. Prepare calculations to show how you are going to prepare your calibration standards.

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?

Polyethylene terephthalate is an example of synthetic material in Materials and Engineering. 1. Describe the relation of its building blocks in connection to its “bulk” (materials) properties. (No need for essay, just a brief scientific explaination!) If you may, please send link as well of the reference that you use for the answer).
A sample of a soil was analysed for K+ as follows. A 2.50 g sample of soil was dissolved in acid and diluted to volume in 100 mL volumetric flask. A 10 mL of the resulting solution was transferred by pipet to a 50 mL volumetric flask and diluted to volume. An analysis showed that the concentration of K+ in the final solution was 9.81 ppm. What was the weight percent of K+ in the original soil?
