A group of students were trying to experimentally determine the density of an unknown liquid. They developed a standard technique for measuring density by recording the mass of a liquid using an analytical balance. The volume of the liquids were accurately measured using a serological pipette and was recorded to be 5.00 mL for each trial. The students were able to collect the following data: Trial 1 (mass in grams) LIQUID Trial 2 (mass in Trial 3 (mass in Theoretical SAMPLE grams) grams) Density Hexane 3.281 3.284 3.279 0.655 g/mL Acetone 3.921 3.923 3.947 0.784 g/mL Ethanol 3.912 3.911 3.913 0.789 g/ml unknown 3.914 3.911 3.910

When we are interested in biological energy resources and metabolism, we need to know, among other things the work that an organism has to do to carry out the normal activities of being alive. How much metabolic E must a bird of mass of 153.3 g exert to fly a height of 6.83 m from earth ground? Neglect all the losses due to friction, physiological imperfection and the acquisition of kinetic energy. Us gravity 9.807 m/s2. Answer in _______ J. 4 sig. number normal format (default is n.f.).
A small amount of resin weighing 4.56g occupies a height of a 10mL graduated cylinder equivalent to one mL. One mL of water was added and the level was read at 1.7 mL. Estimate the density of the resin.
A 795-centigram sample of borax was placed in a certain volume of water at 25 degrees celsius. After adding the sample, the graduated cylinder was read at 35 mL, where a rise of 2.7 mL was observed. What is the weight (grams) of sample? What was the initial volume (millimeters) of water? What will be the weight of displaced water in grams? What is the specific gravity of the solid? What will be its specific volume?
A student decided to undertake a balance calibration exercise during a lab session involving burette calibration. He found the apparent weight of calcium carbonate in air to be 100 grams and density to be 1.33g/mL. Assume that the standard steel weight used in the calibration has a density of 8.0g/mL and air has a density of 0.0012g/mL. What would be the true mass of the calcium carbonate sample?
The mass of a glass beaker is known to be 24.4 gg. Approximately 5 mLmL of water are added, and the mass of the beaker and water is measured on an analytical balance to be 30.625 gg. How many significant figures are there in the mass of the water?
A pipet is used to transfer 6.00 mLmL of a 3.75 MM stock solution in flask “S” to a 25.00-mL volumetric flask “A,” which is then diluted with DI H2OH2O to the calibration mark. The solution is thoroughly mixed. Next, 10.00 mLmL of the solution in volumetric flask “A” is transferred by pipet to a 50.00-mL volumetric flask “B” and then diluted with DI H2OH2O to the calibration mark. Calculate the molarity of the solution in volumetric flask “B.”
A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of glycerol, ethanolamine, pentane, tetrahydrofuran, and dimethyl sulfoxide. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information:
Why do you suppose Km values are so frequently standardized and published, drawing attention to the value Vmax/2, rather than Vmax itself?
Answer the question in full details: Is it possible for a volumetric pipette to have a high precision but low accuracy? How could this situation arise?
If 35,000 kg of whole milk containing 4% fat is to be separated in a 6-hour period into skim milk with 0.45% fat and cream with 45% fat, what are the mass flow rates of the two output streams from a continuous centrifuge which accomplishes this separation? (Ans; Cream=464.8335kg/h, Skim milk= 5368.4998kg/h)
A 139 lb male patient with severe lactate acidosis is given isotonic sodium lactate. The doctor orders isotonic sodium lactate 50. mL/ kg body mass to be administered intravenously. The rate of flow is 150 gtts/min, and the IV administration set delivers 20. gtts/mL, where the unit “gtts” stands for drops of liquid. Calculate what is the running time in minutes will be?

Bobby Drake aka “Iceman” is member of the X-Men who has the physics-defying ability to “manipulate cold and ice.” Iceman is depicted with the ability to lower the temperature of nearby objects at will. For example, Iceman can freeze an entire pond in seconds just by touching the surface of the water. Let’s put some numbers to this example: The pond is 20 m across and can be approximated as a hemisphere. You can assume the density of water is 1.00 g cm–3 and independent of temperature. The temperature of the pond is initially 17°C and uniform throughout. After Iceman freezes the pond, its temperature is –10°C a) How many moles of water are in the pond? b) What is the total amount of heat removed from the pond?
