Nobody mints 100% copper pennies. These days, copper is far too expensive to be minting low denomination coins such as a Penny, and many countries that still produce their lowest single unit of currency coins, do so from steel.
Even in the old days copper was alloyed with other metals to produce "copper" coins.
The closest the Royal Mint ever came to producing a 100% copper coin was in 1944 and 1945 where the copper content got up to 97%. Usually it was 95% copper.

When 12 copper pennies are submerged in water the pennies displace 4.13 cm3 of water If the combined mass of the pennies is 36.93 g what is the density of copper?
The density of copper is 8.94 g/cm3. This can be calculated by dividing the total mass of the pennies (36.93 g) by the total volume they displace (4.13 cm3). This gives the density of copper as 8.94 g/cm3.
How many prior 1981 us pennies does it take to make 100.00 worth of copper?

Is 3 percent equal to 75 percent?
No. The best way to explain this is to look at it as 100 pennies, which equals a dollar. Three pennies would be 3% of a dollar, and 75 pennies would be 75% of a dollar (or 3/4 of a dollar). 3 percent is equal to 0.03, or 3/100, while 75 percent is equal to 0.75, or 75/100. Therefore, 3 percent is much, much less than 75 percent.
How can you have 0 percent of something?
Zero is a number not an idea. If you have no pennies, that means you have zero percent of 100 pennies. If you have one penny, that means you have 1 percent of 100 pennies, or one dollar. Zero like any other number is an indicator of amount. Likewise percentage is also an indicator of an amount of the whole.
How much does 100 dollars in pennies weigh?
If it's dated 1864 to 1909 or from 1959 to mid 1982, then it'd be 31100 grams. But beyond that, it depends on the date. Pennies in the United States began minting in 1787, and then were made of solid copper. The Indian Head penny, the coin to follow, was minted from 1859 to 1864 and varied in content of copper from one hundred percent to eighty-eight percent (the additional metal in the coin was zinc). Based on that variance, pennies from the 1800s can be distinguished by weight. Ninety five percent copper pennies weighed 3.1 grams, but the eighty-eight percent copper pennies weighed 4.67 grams. There is some debate as to the make up of the Indian Heads, and whether or not the print on the coin changed before the metals changed, but the history there gets blurry. Later, during the Second World War, pennies were all made of steel and coated in zinc because the copper was being dedicated to war use. These pennies only weighed 2.7 grams. Modern pennies though, which were introduced with the Lincoln Memorial on the back in 1959, weigh 2.5 grams. Although, pennies produced before 1982 actually weigh 3.1 grams. That being said, one hundred dollars in post 1982 pennies weighs 25,000 grams, or 25 kilograms. I got that by multiplying 100 pennies per dollar by 100 dollars, getting 10,00 and multiplying that by 2.5. 1000 grams is a kilogram, giving me 25 kilograms.
