Amaterial will float on the surface of a liquid if the material has a density less than that of the liquid. Given that the density of water is approximately 1.0g/mL under many conditions, will the block of material having a volume 1.2 x 10^4 in ^3 and weight 3.5lb float or sink when placed in a reservoir of water?
(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?

If you want to deliver 300. mL of a 5.0% glucose solution over a 2.0 hour time period using an IV drip that delivers 18 gtt per milliliter, what flow rate in drops (gtt) per minute is needed for the IV? Select the correct menu items to show how to set up the calculation using dimensional analysis. After setting up the problem, select the final answer from the menu. (Hint: To end with a volume unit over a time unit (gtt/min), you need to start your calculation with a volume unit over a time unit.)
