Part D In parts B and C, you measured the average mass of each group of pennies. Now you'll measure their volume. (For this part, assume that the pennies dated before and after 1982 have the same volume. ) Follow the steps to complete the table. If you're planning to use a graduated cylinder, watch this video on measuring volume before continuing. A Stay safe! Be careful when handling glass containers so they don't break. 1. Add water to the narrow transparent container until it is about half full. 2. Stick a piece of tape to the outside of the container to mark the water level. The water level must be even with the top edge of the tape. 3. Using a graduated cylinder or a teaspoon measure, add another 5 mL (1 teaspoon) of water to the container. Be sure your measurement is exact. 4. Stick another piece of tape to the outside of the container to mark the new water level. This time, the water level must be even with the bottom edge of the tape. Your setup should look something like this c. 5. Next, remove 5 mL (1 teaspoon) of water from the container. The water level will again be even with the top edge of the bottom piece of tape. (Alternatively, pour out all the water from the container and refill it to the top edge of the bottom piece of tape. ) 6. Add pennies one at a time until the water level is even with the lower edge of the top piece of tape. In the table, record the number of pennies added. The pennies you added just displaced about 5 mL of water. 7. Divide 5 mL by the number of pennies added to determine the average volume of each penny. Record this value in the table.
