(a) To identify a liquid substance, a student determined itsdensity. Using a graduated cylinder, she measured out a 45-mLsample of the substance. She then measured the mass of thesample, finding that it weighed 38.5 g. She knew that the substancehad to be either isopropyl alcohol (density 0.785 g/mL)or toluene (density 0.866 g/mL). What are the calculated densityand the probable identity of the substance? (b) An experimentrequires 45.0 g of ethylene glycol, a liquid whose densityis 1.114 g/mL. Rather than weigh the sample on a balance, achemist chooses to dispense the liquid using a graduated cylinder.What volume of the liquid should he use? (c) Is a graduatedcylinder such as that shown in Figure 1.21 likely to afford theaccuracy of measurement needed? (d) A cubic piece of metalmeasures 5.00 cm on each edge.

Janet has a 2 month old baby suffering from a bacterial infection. The baby’s weight is measured as 15.0 lbs and is prescribed Amoxicillin, which is reconstituted in a suspension at a concentration of 200.0 mg of Amoxicillin / 5.0 mL of suspension. She needs 30.0 mg of Amoxicillin per kg of body weight per day. How many total mg of Amoxicillin will she need per day? If she needs to take the medication twice a day, how many mL of the drug (suspension) should she be given in each dose?
An experiment with a pycnometer resulted in the following data: Mass of Pycnomter = 25.428 g Mass of Pycnometer filled with water = 44.021 grams Mass of Pycnometer filled with liquid X = 41.421 grams a) What is the specific gravity of liquid X? b) If methanol (Specific Gravity = 0.790) was used rather than water in measuring the density of irregular objects, how would that affect the result? Why?
Specific gravity is important for diagnosing various health conditions, such as dehydration. The normal specific gravity falls between 1.002 - 1.030. Mild dehydration is indicative from specific gravity that is greater than 1.010 and the higher the value the more dehydrated one may be. A 25 year old female patient wastaken to the hospital with symptoms of extreme thirst, fatigue, and headaches. An 0.0077 liter urine sample was taken for the patient described above. The sample had a mass of 8.05 grams.
