The purpose of this lab was to mother out how many pennies in that respect were inside the involve canister, and determine how on that point were pre 1982 pennies and after 1982 pennies.

supposal
If there was 26.52g of just pennies inside the film canister, then there is 6 after pennies and 4 before pennies.
Materials
* 14 Pennies
* 5 take canisters (one of them has to be filled with 10 pennies)
* Scale
* Calculator

execution
1. First weigh out the canister filled with pennies
2. past get 14 pennies (7 pre and 7 after) and weigh them out
3. Get sightly of each
4. Then weigh 4 film canisters, and find average
5. Now get the weight of the filled canister and recoup it by the weight of the canister, and then that will get you the adjudicate weight of only pennies.
6. Now guess what you think the number of each penny is inside that canister.

Data
The weight of the pre pennies, the after pennies, and film canisters
Pre 1982 pennies| After 1982 pennies| Film canisters|
3.12g| 2.49g| 6.89g|
3.09g| 2.50g| 6.25g|
3.05g| 2.48g| 6.96g|

03g| 3.12g| 6.26g|
3.08g| 2.49g| |
3.10g| 2.45g| |
3.10g| 2.50g| |
The weight of the canister filled with pennies was 33.11g.

Averages
Pre
3.12+g3.09+3.05g+3.03g+3.08g+3.10g+3.10g = 3.08g

After
2.49g+2.50g+2.48g+3.12g+2.49g+2.45g+2.50g = 2.58g

Film canister
6.89g+6.25g+6.96g+6.26g = 6.59g
4
33.11g-6.59g= 26.52g of just pennies
