What is the density of 10 pennies?
To find density you must first determine the mass and volume. Also, it matters if your penny or penny's are pre 1982 or post due to the metal they were created in. 10 post '82 penny's will weigh in approx. 25.0 grams. To get your volume = 3.14 X radius squared x height. In this case it would look like V = 3.14 x 9.5mm x 9.5mm x 1.27mm. Whereas V= 360 cubic millmeters. To get your density, we use Density = Mass/Volume. So Density=25\360, which equals .0694 g/cubic millimeters.
How can you calculate the thickness of 1 penny in millimeters?
You can get a stack of pennies, measure the height of the stack and then divide by the number of pennies. You can also get the thickness by treating the penny as a cylinder, calculating the area of the face of the penny, then putting a whole lot of them in water, measuring the change of volume to get the total volume of all pennies, then divide by the number of pennies and divide again by the area of the penny to get the thickness.
What is the volume of 200 pennies?
There are very many countries which use pennies as their minor currency units, including the US where, for some bizarre reason, a cent is also called a penny. The country is not specified. Assuming it is the UK and that the embossing adds so volume, 200 penny coins will have a volume of approx 107 millilitres.
What is the percentage of copper in a 2004 penny?
All US cents minted for circulation since mid-1982 are 97.5% zinc, plated with 2.5% copper.
What year of minting make a penny worth more than its face value?
If it was minted before 1982 it contains 95% copper and is worth about 2 cents in melt value.
What is the weight and length of a penny?
Pre-1982 Lincoln cents weigh 3.11 grams and have a diameter of 19mm, 1982 to date weigh 2.5 grams with the same diameter.
Which is heaver a 2006 penny or a 1982 penny?
Probably the 1982 penny if it's a copper version.
How can you tell if a 1914 d penny is a replica?
Check the weight. Copper pennies (pre-1982) should weigh 3.11 grams.
Is a US penny copper?
Pre-1982 pennies are made of bronze, which is 95% copper plus 5% tin and/or zinc. Post-1982 pennies are zinc with a thin coating of copper.
Is the copper scrap value worth more than face value of a pre 1982 us penny?
Yes. As of January 14, 2010, with copper at $3.3764/lb and zinc at $1.1251/lb, a pre-1982 penny (95% copper and 5% zinc) has a "melt" value of 2.23774 cents. See the website http://www.coinflation.com/ for current "melt" values.
What is a good home product to use to clean a penny?
If its pre-1982 ketchup works. Just put on a dab and wait a min and wipe it off.
Does copper rust or tarnish?
It does not rust. It oxidizes and tarnishes. The bright red color of clean, new copper will burnish into a dull brown. Look at a penny... a pre 1982 US penny is 95% copper and 5% zinc.
Does a penny have more atoms than earth does people?
Yes, most definitely, a penny has many more atoms than the Earth does people.A pre-1982 penny contains about 28,000,000,000,000,000,000,000 copper atoms. Or, 2.8 x 1022atoms.There are about 6 billion people on the planet.

Which is more dense a penny from before 1972 or a penny from after 1972?
1972 has no significance in terms of changes in penny densities. The US Mint did not change the composition of its penny between 1909 to 1982, so any pennies from within this time period would have the same density. Pennies from this time period all contained the same proportions of metals (95% copper, 5% zinc.) Coins from post-switch 1982 to present day are minted of 97.5% zinc and 2.5% copper. Copper's density is ~8.9g/cm3 while zinc's density is ~7.1g/cm3. Considering the relative compositions of each version of the penny, the post-1982 penny would be the less dense penny, and the pre-1982 penny would be the more dense of the two.
How much of a penny's weight is copper?
If the penny was made pre-1982, it weighs 3.11 gm and is made of bronze containing 95% copper. That means it contains 0.95 * 3.11 = 2.955 gm of pure copper. If the penny was made post-1982, the penny will weigh 2.5 gm and be made of 97.5% zinc with a coating of copper, so it only contains 0.025 * 2.5 = 0.0625 gm of pure copper.
How much does a copper penny weight?
Pre-1982 copper pennies weigh 3.11 grams. Pennies made since then are mostly zinc and weigh 2.5 grams.
