Recently, P. K., has had bouts of such sadness that he stays in bed and calls in sick to work. This has become problematic for the company he works for as there are few substitutes to call in to take his place in his particular job. He reports that when this overwhelming sense of sadness comes over him, his whole body feels immobilized though he rarely cries, He has no energy to even take a shower so he sleeps as much as he can. He reports that he will stay in bed until he feels a “burst” of energy. When that happens, he cannot sleep at all. He goes out walking the dark streets at night looking for something to do or someone to talk to. The last time this happened he stopped at an all-night convenience store. He spent the $25.00 dollars that he had in his pocket on gum. Then he used his credit card to buy $250.00 worth of candy and asked the cashier to give it away to other employees or children that might come into the store the next day. The cashier called the police when she witnessed him as he left the store singing out loudly and yelling at cars passing him as he walked in the middle of the street.

Directions: Clearly show the setups for your calculations. 1. You wish to prepare 50.0 mL of $2.30 \times 10^{-2}$ M solution 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. Show any required calculations you would need to make. 2. Calculate how many milligrams of the drug are contained in 2.0 mL of a 3.0% (wt/vol) solution of your drug.

Texts: Hello, I just need help completing question #8 where it asks for the answer in Kilometers and Miles. This is for Astronomy, and I am having a hard time figuring out what I need to do next. Thank you for the help! 6. Repeat step 5 for flying from Earth to Pluto. Show your work! V=600,000,000 km/h S = 6,200,000,000 km V = 600 m/s t = S/V t = 6,200,000,000 km / 600 m/s t = 10,333,333.33 s 7. The star nearest to our Sun is Alpha Centauri, which is 4.3 light years away. A light year is the distance that light travels in one year. 1 light year is about 9,500,000,000,000 kilometers. How many astronomical units is it to Alpha Centauri? Show your work, not just only the result. 1 light year = 9,500,000,000,000 km 4.3 light years = 4.3 * 9,500,000,000,000 km = 40,850,000,000,000 km 1 astronomical unit (AU) = 150,000,000 km 40,850,000,000,000 km / 150,000,000 km/AU = 272,333.33 AU 8. On a scale model (1 AU = 7 m), about how far would you have to walk to put a tennis ball the right distance away from the Sun to stand for Alpha Centauri? Show your work, not just only the result. 273,333.33 AU * 7 m/AU = 1,913,333.31 m Convert your answer to kilometers: 1,913,333.31 m = 1,913.333.31 km Convert your answer to miles: (Note that one mile equals 1.609 kilometers) 1,913,333.31 km / 1.609 km/mile = 1,189,133.33 miles

3. Consider the data given in the table below for the temperature changes in a 10,000-liter fermenter, including heat-up and cool-down periods. Assume an intial spore concentration of $10^5$/liter and a vitamin concentration of 30 mg/liter. The values for the Arrhenius parameters for the spores are $K_{do}=1 \times$ $10^{36}$/min and $E_d=65$ Kcal/mol. The values of the Arrhenius parameters for the degradation of vitamins are $K_{mo}=1 \times 10^4$/min and $E_m=10$ Kcal/mol. Using a numerical approach, calculate the following: a. What is the probability of a successful sterilization? b. What fraction of the vitamin remains undegraded? c. What fraction of the vitamin is degraded in the holding period? d. What fraction of the vitamin is degraded in the heat-up and cool-down periods? e. What is the fraction of spores deactivated in the heat-up and cool-down cycles? t (min) 0 10 20 30 40 50 55 60 65 70 90 100 120 140 T (°C) 30 40 54 70 95 121 121 121 106 98 75 64 46 32
