CHEM 10050 Problem Set #3 Name_________________ 1. Calculate the molarity of normal saline (0.90% w/w NaCl) given the density of this solution to be 1.05 g/ml. Assume 100 g solution. Then: [pic] [pic] [pic] [pic] 2. Calculate the molarity of an aqueous solution resulting when 275 ml of 3.15 M glucose is diluted with 150 ml of water.
LABORATORY REPORT Activity: Name: Instructor: Date: Blood Glucose Regulation Miranda Parker Jill Schmitt 10.03.2014 Predictions Plasma glucose levels will be highest immediately after the meal (0 hr) Plasma ketone levels will be highest before the meal (fasting) Plasma insulin levels will be highest 1-3 hours after the meal Plasma glucagon levels will be highest 1-3 hours after the meal Materials and Methods Dependent Variable plasma levels of glucose, ketones, insulin, and glucagon Independent Variable food and beverage intake Controlled Variables physical activity, caffeine and alcohol intake, gender, age, BMI 4. Why were physical activity and caffeine and alcohol intake the controlled variables? Because you can control on the amount of time you spend doing physical activities and the intake of both caffeine and alcohol. 5. What type of assay was used to measure plasma glucose and ketone levels?
I believe this will happen because the more sugar molecules there are at the same time, the longer it will take for them to find space inbetween the water molecules. Aim Does the amount of sugar affect how fast the sugar dissolves? The experiment The experiment was based on dissolving different quantities of sugar in 100ml water at 60ºC and to keep track of how much time it took for the sugar to dissolve. We made sure that we used the same amount of water in each trial, and that the temperature was maintained at 60ºC. I think that if we do not have the same amount or the same temperature, we might influence the experiment in a way that would make it impossible to tell if the amount of sugar to be dissolved had an influence on time.
Your answer : b. The hemoglobin levels for these two individuals will be the same. Stop & Think Questions: Why is the average hematocrit higher in males than in females? You correctly answered: c. Higher testosterone levels in males promotes more RBC production.

LABORATORY REPORT Activity: Influence of Fluid Intake on Urine Formation Name: Marlinda Saintil Instructor: Florence Vicil Date: 05.04.2015 Predictions Urine output will be highest during water loading Urine osmolarity will be highest during dehydration Plasma osmolarity does not vary much during dehydration and water loading Materials and Methods Dependent Variable urine and plasma values Independent Variable fluid intake Controlled Variables room temperature, age, gender, and weight 4. Subjects were asked to refrain from alcohol and caffeine for a day before the start of the experiment. Explain why this is important. 5. What technique was used to measure urine and plasma osmolarity?
Diffusion and Osmosis Lab Part 1A: Diffusion Evidence: Table 1: The Color of Different Solutions Before and After Diffusion for 30 Minutes Content | Initial Solution Color | Final Solution Color | Bag15% glucose1%starch | Cloudy white | Very dark purple | BeakerWater + IKI | Golden yellow | Golden yellow | The above table represents the final and initial colors of the solution that was inside of the dialysis tubing and the solution that was in the beaker. A 15% glucose and 1% starch solution was placed inside of the dialysis tubing. The initial color of the solution in the bag was a cloudy white but after 30 minutes of sitting in the beaker of water and IKI the color turned a very dark purple almost black. Inside of the beaker was a water and IKI solution. After sitting for 30minutes this solution stayed the same color.

CLINICAL PHARMACOLOGY Absorption: Zyloprim is approximately 90% absorbed in the gastrointestinal tract. Peak plasma levels generally occur at 1.5 hours and 4.5 hours for Zyloprim and oxipurinol. Excretion: Approximately 20% of the ingested Zyloprim is excreted in the feces. Because of its rapid oxidation to oxipurinol and a renal clearance rate approximately that of glomerular filtration rate, Zyloprim has a plasma half-life of about 1 to 2 hours. Zyloprim is cleared basically by glomerular filtration.
