Density of Metal Stacked Metal Coins
1. Obtain the mass of 5 coins of the same denomination. Note if you are using
pennies, nickels, dimes, or quarters. 24.84
2.
Measure the diameter of the stack of the coins in cm. Use this measurement
to determine the radius of the coin stack.
3.
Measure the height of the stacked coins in cm.
4. Using the formulas in the data collection page, determine the volume of the
coins.
5. Using the mass and the volume of the coins, determine the density of the coins.
6. Using the accepted value for the metal coin density, determine the percent error.
