INTERACTIVE EXAMPLE Determining Density At a local pawn shop a student finds a medallion that the shop owner insists is pure platinum. However, the student suspects that the medallion may actually be silver or aluminum, which are much less valuable. The student buys the medallion only after the shop owner agrees to refund the price if the medallion is returned within two days. Th student, a chemistry major, then takes the medallion to her lab and measures its density as follows. She first weighs the medallion and finds its mass to be 55.64 g. She then places some water in a graduated cylinder and reads the volume as 75.2 mL. Next she drops the medallion into the cylinder and reads the new volume as 77.8 mL. Is the medallion platinum (density = 21.4 g/cm3), silver (density = 10.5 g/cm³), or aluminum (density = 2.70 g/cm³)? HOW DO WE GET THERE? Determine the density of the medallion.

One day on a walk you find a tiny piece of a meteor. Lab analysis determined it was 1.24 percent mass (percent composition) of Iridium, a very rare and expensive metal. If on a second walk you discover the main fragment of a meteor with a mass of 5 kg. what mass of iridium makes up the meteor? Show work
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?

The density of a metal is 8.67 g/cm. How many pounds are in 298.86 in of the metal? (You can use the conversion factor approach. Or, you can convert density in g/cm? to Ib/in and then thultiply the result times number of pounds. 2.52 cm 1 inch 454 g = 1 lb Please see 'answers to extra problems' question 10 for hints on how to do this.) You need to write your answer in the box with one number past the decimal. Please don't worry about the sig figs in this case. In these formula problems, the Canvas software will give a variety of questions and each student gets their data with different sig figs. So I just have to choose and sometimes it might seem that one past the decimal is not the correct sig figs. Nonetheless, you have to follow that direction.

For this method to work the solid must (a) be more dense than the liquid, and (b) not react with nor dissolve in the liquid. Water will be a suitable solvent for determining the volume of metals in this lab. An irregular shaped piece of metal has a mass of 131.0 g. You put it into a 100 mL graduated cylinder containing 22 mL of water, and the water level rises to 68 mL. What is the density of metal in g/mL? g/mL Calculator Submit Question
Imagine that you took a road trip. Based on the information in the table, what was the average speed of your car? Time 3:00 pm 8:00 pm Mile marker 14 265 Express your answer to three significant figures and include the appropriate units. Use mi as an abbreviation for miles, and h for hours, or mph can be used to indicate miles per hour.
1. Why are units so important in measurement? Giving examples of measurements with no units should help. 2. What does it mean to say that 2 expressions are equivalent?
