What is the mass of one mole of pennies?

Answer 1

Assuming you are referring to United States Lincoln cents: 1909-1981 (except 1943) (95% Copper and 5% Zinc) - 3.11 grams (147 to the pound) 1943 pennies are steel with a zinc coating and weigh about 2.7 grams (about 168 to the pound). 1983- to date (2.5% Copper and 97.5% Zinc) - 2.500 grams (181 to the pound) In 1982, both the 95% copper and 97.5% zinc varieties were made - there is no easy way (other than by weighing them) to differentiate between them. To convert grams to ounces, divide by 28.35

Answer 2

In the English system, the average weights of the various denominations are:

One penny piece = 3.6 g or 0.12 Oz;

Two penny piece = 7g or 0.22Oz

Five pence piece = 3.3g or 0.11Oz

Ten pence piece = 6.5g or 0.21Oz

Twenty pence piece = 5.0g or 0.16Oz

Fifty pence piece = 8.0g or 0.26Oz

One pound coin = 9.5g or 0.31Oz

Two pound coin = 12.1g or 0.39Oz

These are the only coins I have the ability to weigh.

Answer 3

1983 and later US cents weigh 2.5 grams and are 2.5% copper so they have 0.0625 gm of copper. The rest is zinc.

1981 and earlier cents weighed 3.11 gm and were 95% copper.

1982 cents can be either; the composition was changed in mid-year.

Answer 4

While it's not meant to be used this way, one could say that one mole of pennies, using Avogadro's number is 6.02 x 10^23 pennies.

And since, according to the US mint, the penny should weigh 2.5g

then the total would be 1.505 x 10^21 kg

Answer 5

A United States penny is 1.52 mm thick. So a mole of pennies stacked upon each other would be a lofty tower of 9.15x10^17 km.

1.52 mm/penny * 6.022x10^23 pennies = 9.15x10^23 mm

9.15x10^23 mm (0.001 m/mm) (0.001 km/m) = 9.15x10^17 km

To put this in perspective, the Sun is 1.5x10^8 km. That means a mole of pennies could make 6100000000 stacks of pennies that go to the sun.

9.15x10^17 km / 1.5x10^8 km/stack = 6.1x10^9 stacks

Answer 6

There are many countries which use the term "penny" to denote their minor currency units - including the US where they choose to call a cent a penny! These have different sizes, different compositions and so the masses will be different. The answer depends on which country, but this has not been specified.

Answer 7

The pennyweight, or dwt, was a unit of mass equal to 1/20 of a troy ounce, and 1/240 of a troy pound. It is equal to 1.55517384 grams.

Answer 8

The weight of one penny is 2.5 grams. It has a diameter of 19.05 millimeters and a thickness of 1.52 millimeters.

Answer 9

1 mole = 6.022x10^23 particles

1 mole = 6.022x10^23 atoms

1 mole = 6.022x10^23 molecules

1 mole = 6.022x10^23 pennies

1 mole is always equal to 6.022x10^23 things.

Answer 10

The English penny is not a pure metal.
