5. The volume of an irregularly shaped solid can be determined by immersing the solid in a liquid and measuring the volume of liquid displaced. Find the volume and density of the following:
a. An irregular piece of the mineral quartz is found to weigh 12.4 g. It is then placed into a graduated cylinder that contains some water. The quartz does not float. The water in the cylinder was at a level of 25.2 mL before the quartz was added and at 29.9 mL afterward.
b. The volume of a sample of lead shot is determined using a graduated cylinder, as in part (a). The cylinder readings are 16.3 mL before the shot is added and 21.7 mL after. The sample of the shot weighs 61.0 g.
c. A sample of coarse rock salt is found to have a mass of 11.7 g. The volume of the sample is determined by the graduated cylinder method described in (part a), but kerosene is substituted for water because the salt will not dissolve in kerosene. The cylinder readings are 20.7 mL before adding the salt and 26.1 mL after.
There are 12 inches in 1 foot and 3 feet in one yard. There are 1760 yards in 1 mile.
a. How many miles are in 1345 feet?
b. How many yards are in 75 inches?
c. How many square inches (in2) are in 3.5 yd2 ?
