Use the References to access important values if needed for this question. A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, she used the ideas just developed in class about density. She measured the mass of the metal to be 323.0 grams. Then she dropped the metal into a measuring cup and found that it displaced 16.5 mL of water. Calculate the density of the metal.

Here are two possible methods for measuring the volume of an irregular shaped object: a) Add it to a graduated cylinder containing a known volume of water. Measure the change in the volume of the water after the object has been added. The graduated cylinder is graduated in 1 mL increments. b) Add the object to a vessel that is full of water. Collect and measure the mass of the water that is displaced on a digital balance that provides mass to the 0.001 g. Determine the volume using the tabulated densities of water in table 1.1. Which method would be more likely to produce a more precise measure of the volume of an object?

1. A student weighs an empty special round bottom flask and stopper. He finds the mass to be 56.972 g. He then adds about 5 mL of an unknown liquid and heats the flask in a boiling water bath at 100°C. He allows all the liquid to vaporized and then removes the flask from the bath, stoppers it, and lets it cool. Upon cooling, he briefly removes the stopper, then replaces it and weighs the flask and condensed vapor, obtaining a mass of 57.917 g. The volume of the flask is known to be 240.2 mL. The barometric pressure in the laboratory that day is 743 mm Hg. What was the pressure of the vapor in the flask in atm? O 0.9776 atm 0.98 atm 0.978 atm 0.977 atm
