The purpose of this lab was to mother break how many pennies in that respect were inside the involve canister, and determine how on that prove were pre 1982 pennies and after 1982 pennies. supposal If there was 26.52g of exclusively pennies inside the postulate canister, then there is 6 after pennies and 4 earlier 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 separately 4. whence weigh 4 icon canisters, and find average 5. directly get the encumbrance 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 th e 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| 3.03g| 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.
