GenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect normal levels of dissolved fibrinogen (200. to 400. mg dL), using a blood sample that is as small as 250 µL. Calculate the minimum mass in milligrams of fibrinogen that the new system must be able to detect. Be sure your answer has the correct number of significant digits.
You are asked by the King of Allegesia to determine if the crown he was given for his birthday is pure gold. The density of pure gold is 19.32 g/mL; the density of water is 0.998 g/mL at 20ºC. There is a container when filled to the mark contains 1900.0 mL. When the container is filled with water to the mark, it has a mass of 2499.5 g. The crown is placed in the container and filled to the mark with water and now weighs 15,113.3 g. The crown has a mass of 13,910.0 g. What is the density of the crown? Is the crown pure gold?
2. A small block of a metal with a mass of 223.1 grams when submerged in a beaker containing water, the water level rises to 150.0 mL as shown in the figure here. If the density of the metal block is 7.41 g/cm at 22°C, then what was the original water level Water level 150 mL in the beaker? Metal block-

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.
