How many 2011 pennies make a ton?
The answer will depend on pennies for which currency, in which country. Th UK penny - which is a penny has quite a different mass to a US penny which is not even a penny, but a cent!
There are a 1000 pennies in a jar without removing any pennies explain how you can find the mass of one penny?
the question is too vagueif you're allowed to use a good weighing machine then weigh the total jar and divide the answer by 1000 (saying the glass jar has negligible weight and the mass of air negligible)if you know the mass of the glass jar then minus the total weight with the glass jars and then divide by 1000otherwise if you're not allowed to use a weighing machine you can use the water method which would be a bit more complicated. (there are other method to find the weight using vacuum)And moreIt's even more complicated than that! Not all pennies have the same mass, so the experiment is very ill-defined. Pennies (cents, really) made before 1982 have an average mass of 3.11 gm, while cents made after that year have a mass of 2.5 grams. If that's not confusing enough, cents specifically dated 1982 can have either mass depending on where they were made and at what time of the year. IN ADDITION....to answer the original question proposed. If you take the jar full of pennies and put it on a scale. Then add a single penny to the jar already full of pennies the weight will increase. This being done one can now subtract the added weight from the original weight of the full jar to find the weight of a single penny
How many pennies make an oz?
From the US Mint, a penny has a mass of 2.500 grams. There are 28.35 grams in an ounce, so (28.35)/(2.500) = 11.34, so 11 pennies is almost an ounce.
What is the mass of a US penny nickel and dime?

How much would 1000000 million pennies weigh?
That would depend on what pennies you are talking about (i.e., from what country). Look up the weight of the penny for your particular country, then multiply it by a million. Here is a list of pennies:http://en.wikipedia.org/wiki/Penny#List_of_penniesFor example, the U.S. penny has a mass of 2.5 gram; multiplied by a million gives you 2500 kg. or 2.5 tonnes.
How does the density of one penny compare with the density of two pennies?
The density of two pennies would be greater than the density of one penny, as the mass of two pennies is double that of one penny while their volume remains the same. Therefore, the total mass is concentrated in a smaller volume, resulting in a higher density.

How much is 38lbs of pennies equal to in dollars and cents?
A US Penny has a mass of about 2.5 grams. There are about 453.59237 grams in a pound. This means there are 453.59237/2.5 = 181.436948 pennies per pound. So 35 pounds times 181.436948 pennies per pound = 6350.29318 total pennies. So rounding to the nearest whole number gives us 6350 pennies, for a total of $63.50.
How many pennies have the same mass as 6 liters of water?
6 liters of water weigh approximately 6000 grams. A penny weighs about 2.5 grams. So, to find how many pennies have the same mass as 6 liters of water, you would divide 6000 grams by 2.5 grams per penny, which is 2400 pennies.
How does the mass of zinc penny compare to a copper penny?
A zinc penny has a lower mass compared to a copper penny. This is because zinc is less dense than copper, so a zinc penny is lighter than a copper penny of the same size.
How many pennies make 500 grams?

A pre-1982 penny has a mass of 3.1 grams and a post 1982 penny has a mass of 2.5 grams How many pennies of each type are there if the mass of 20 of them is 61.16 grams?
Let x be the number of pre-1982 pennies and y be the number of post-1982 pennies. You can create a system of two equations based on the information given: 3.1x + 2.5y = 61.16 (total mass equation) x + y = 20 (total number of pennies) From there, you can solve for x and y to find out how many of each type of penny there are.
What is the average mass of one penny?
The average mass of one U.S. penny is approximately 2.5 grams.
How much is 2009 penny worth?
2009 pennies were made in mass productions. Currently a 2009 penny is only worth a penny unless it is a proof. If it is a proof it will have the mintmark "S" below the date.

Do pennies gain mass over time?
Yes, pennies can gain mass over time due to oxidation and corrosion which can cause the surface to accumulate dirt and contaminants. This can make the penny weigh more without actually adding metal.
