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?

You cant't figure this out using copper pennies. Pennies are not 100% copper.

What is the density of a penney?
Since pennies are mostly zinc the density is approximately 7.2
What would happen to an objects density if you multiplied the amount of objects?
Nothing at all. The density of one penny is the same as the density of a truckload of pennies, or of a cargo-ship-load of the metal that's used to make pennies out of.
Why do pennies before 1982 have a higher density than 1982?
Up into 1982, US pennies were 95% copper, but that year the composition was changed and now they're 97.5% zinc.
How much does 1000000000 pennies weigh?
It depends if you are talking about pre-1982 pennies or post-1982 pennies.
Why do the new pennies have less mass than the old pennies?
The newer pennies have a different proportion of metal

What does vinegar do to pennies if submerged for three days?
There is acid called ACETIC ACID it combines with the copper to form a copper acetate(the green coating on the pennies)!!!!!!!!!!!!!!!!!! coiol huh

Which is more dense a stack of 5 pennies or a stack of 20 pennies?
Neither is. Density only depends on the substance, not on how much of it there is.
does a coin sink or float?
The reason the pennies sink in water is because of an idea called density. The pennies have more density than the water, and so the pennies sink. Anything with more density than water will sink in water, but other objects that have less density than water will float.
What is the combined diameter of 2 pennies to the nearest one fourth inches?
1/8
How many professional life pennies were made in 2009?
The combined mintage from all 3 mints is 654,172,373
Does six pennies mean six pence?
A Sixpence was a small silver coin used in many countries of the British Empire that was the equivalent in value to 6 pennies, hence the name. Sixpence is also how you would refer to the combined value of 6 pennies. If you had 6 pennies, or 3 pennies and a Threepence in your pocket, you could say that you had sixpence in your pocket.
Why do pennies before 1982 have a higher density than 1982?
Up into 1982, US pennies were 95% copper, but that year the composition was changed and now they're 97.5% zinc.
How do you calculate percentage error for density of pennies?
Percent error refers to the percentage difference between a measured value and an accepted value. To calculate the percentage error for density of pennies, the formula is given as: percent error = [(measured value - accepted value) / accepted value] x 100.
What year did they make the most pennies?
To date, the year with the highest mintage was 2000, with a combined mintage of over 14 billion.
If water splashes out of a graduated cylinder during a measurement of the volume of pennies Will it affect the results?
Measuring the volume of pennies by their displacement requires that only water actually displaced by the pennies is measured. Unless the water was at the very top of the cylinder both before and after the pennies are added, splashed water will make the measurement invalid.Because surface tension forms a curved surface at the top of the water, it is advisable to have the cylinder only partly filled, and measure the level at the same part of the curved water surface both before and after the pennies are added. This will improve the accuracy of measurement.
