Question

volume and density

The normal range for the specific gravity of human urine is listed as 1.003 to 1.030. Do you expect the specific gravity to be elevated or depressed when a person is dehydrated? Give reason for your answer 2 Manufacturers of carbonated beverages have tanks containing carbon dioxide gas. Carbon dioxide is 1.5 times denser than air. Suppose there is a leak in the carbon dioxide gas tank, the concentration of carbon dioxide in low-lying compartments, especially those below ground level, increases to dangerous levels. Explain why the carbon dioxide level is higher in lower levels than in upper levels. 3 4. In an experiment, a student determined the density of a liquid to be 0.875g/ml. Suppose the actual density of the liquid at that temperature is 0.840 gml. Calculate the percent error in the student's experimental value. Show work!
