Both are units of weight, but it means mass ofthe drug per mass of the patient's weight. The LD50 (lethal dosage, 50%: the dose at which 50%of lab rats die when given this dosage. Dosages at or above this level are considered lethal.) ofdrinking alcohol, or ethanol, is about 7 g/kg. If a 180-pound man were to drink half a 750 mLbottle of vodka that is 40% alcohol by volume, has he drunk a potentially lethal dosage ofethanol? The density of ethanol is 0.789 g/mL.tv

Given the LD50 of ethanol = 7 g ethanol / Kg body weight or 7 g / Kg Given the weight of the man =…

Quantitative analysis student Jon analyzed an ore sample for its lead content and obtained a mean of 4.75% Pb for five measurements. If the certified true value is 4.50%, what is the (a) percent error? (b) percent accuracy?
Using the data below (included for context), what is the equation for the trendline for the data points that fall in the linear range (linear range was found to be timepoints 1 min to 4 min,)? Your answer should be in the form of y = mx + b. Make sure that your trendline only includes the data points that fall in the linear range. In order to determine the trendline using Excel, you may need to create a new graph that only includes the earlier data points. With your new trendline, what is the initial velocity when 1 nM OXA-M290 is mixed with 60 μM nitrocefin? Make sure to include units in your answer. Context: DO NOT ANSWER Concentration of hydrolyzed nitrocefin at 20 time points.

Sarah bought a neti pot from©. After using up the salt packets she decided to make one from scratch at home. After some Internet research she found out that for every 8 ounces (oz.) of water, she should mix in 1/4 teaspoon (tsp.) of pure non-iodized salt (sodium chlodide, NaCl). Conversion Chart: 1 oz. of water = 29.5738 mL Density of Water = 0.997 g/mL 1 tsp. of salt = 5.9985 g Answer the following: 1.) What will be the molarity (M) of the solution? 2.) What will be the molality (m) of the solution? (Use density of water to find kg of water). 3.) What is the mole fraction (X) of salt in the solution? Extra Credit: Sarah is unsure about the type of water to use (tap, bottled, or distilled). What do you recommend and why?

The physician of patient AJ (50 kg, M) admitted in your hospital ordered that the patient receives 0.25 mL of drug A per kg of body weight. This must be mixed with 250 mL of D5W. The IV admixture must be administered over a six-hour period only using a drip set capable of delivering 15 drops per mL. Your pharmacy has stocks of 2.0% w/v of drug A solution (density of drug A: 1.2 g/mL). Answer all questions below. 1. How many mL of drug A must the patient receive to obtain the needed dose? 12.5 mL B. 25.0 mL C. 50.0 mL D. 75 mL 2. From the pharmacy’s stocks of drug A solution, how many mL must be added to 250 mL D5W to prepare the IV admixture? 250 mL B. 500 mL C. 750 mL D. 1000 mL 3. What is the total volume of the admixture that will be administered to the patient? 262.50 mL B. 500 mL C. 750 mL D. 1000 mL 4. Given the capability of the hospital’s IV set, how many drops of the admixture should be administered to the patient? 3,936.5 drops B. 7,500 drops C. 11,250 drops D.…
