What is the density of a penny 1982?

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.
What is the density of a penny?
Density is 7.18 g/ml for post 1982 which is quite close to that of Zinc density of 7.14 g/ml. This makes some sense since the coin is 97.5 % Zinc and 2.5 % copper with a density of 8.92g/ml. The mass is: 3.11 grams [pre 1982] 2.50 grams [post 1982] The findings of a physics class: I calculated it in my physics lab with a group of students - To attempt to approximate for the different amount of nickel found in a penny past 1998, we took the avg of ten coins for thickness and mass. The density was found to be equal to 6.60 grams/centimeters cubic (approximately).
What is a post 1982 penny made of?
Copper coated zinc
Which is heaver a 2006 penny or a 1982 penny?
Probably the 1982 penny if it's a copper version.

What is the formula for the post-1982 penny?
If by formula you mean composition, a post-1982 penny is 97.5% Zinc and 2.5% Copper by mass.

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.
What percent copper is a 1984 penny?
Next to none. Post-1982 pennies are only plated with copper, they are mostly zinc. The amount of copper on a post-1982 penny is miniscule and costs more to remove than melt value is.
What has more density a rubber duck or a penny?
A penny has more density.
Which is heaver a 2006 penny or a 1982 penny?
Probably the 1982 penny if it's a copper version.
Which is more dense a pre 1982 penny or a post?
8.869 grams per cubic centimeter approximately. Some 1982 pennies are made of bronze alloy (pre1982) and some are copper plated zinc (post 1982). The change was made at the beginning of 1982 after some pennies had already been struck.
When was the penny post invented?
the penny post was invented in 1888
What is the metal used to make a penny?
Prior to 1982, 95% Copper, 5% tin and zinc, with the exception of the 1943's. Post 1982 = 99.2% zinc, 0.8% copper.
