1. Jack is trying to use a graduated cylinder to measure volume. He puts 75 ml of water into the graduated cylinder. He then places his object into the graduated cylinder. The water level is now 107 ml. What is the volume of Jack's object? How did you figure this out? (Show your work)

Did Archimedes really figure out the volume of the king's crown in the bathtub, then jump out and run around town exclaiming "Eureka!"? Either way, the displacement method of measuring is a convenient way to determine the volume (on the way to density) of some irregularly shaped objects. In the activity shown at right, the volume of the water was reported as 13.98 mL before the object was added, and 18.28 mL after. The mass of the object was found to be 2.387g. What is the density of the object?

Estimate each volume in milliliters, to two significant digits if possible. Include units of ml in the answer. What is the volume of water in the graduated cylinder? What is the volume of water in the beaker? What is the volume of water in the Erlenmeyer flask?
