Find the number of atoms in the thickness of zinc coating in a piece of galvanized steel?

Q: My AP chemistry class was given a challenge. We were each given a piece of galvanized steel (iron coated with a very thin layer of zinc to protect against rusting) and we were instructed to calculate the number of atoms deep the zinc coating was. We started by weighing the galvanized steel and measuring its dimensions. We then dissolved the zinc from the iron by submerging it in a solution of hydrochloric acid. Thus, we were left with just the iron. We then recorded the new weight.Next comes the hard part: calculating the number of atoms in the the thickness of the coating. Here are the measurements:Weight before: 1.0771 gDimensions: 21.5 mm x 17mm x <1mmWeight after: 0.9901 g *The dimensions of the steel we were not significantly changed.I know this question is asking a lot, but any help you can give me woudl be GREATLY appreciated : ) Thanks!

A: Grams of Zn = 1.0771 – 0.9901= 0.087 g ZnMolar mass of Zn = 65.37 g/mol Moles Zn =0.087 g / (65.37 g/mol) = = 0.0013309 mol Zn1 mol = 6.022×10^23 atomsThen:0.0013309 mol Zn * (6.022×10^23 atoms Zn / mol Zn) == 8.014×10^20 atoms Zn

Where can I find Zinc and Cooper Electrodes?

Q: My daughter is doing a scince project for school. It is the battery potatoe thing but a little different. She is trying all types of friuts and vegetables, but i have no clue as to where I can buy zinc and cooper electrodes. Does anyone have any suggestions or any ideas that may help her?

A: This is EASY. Go to a big box home improvement store. Get heavy gage house wire (12 or 10 gage solid) from the electrical department. Have them pull you some by the foot and get five feet or so. House wiring is made of copper. Next head over to the hardware department. Find some zinc coated nails. Use those as electrodes. The demo I like to do is to take an LCD clock and hook it to a potato battery. It also works with soda, oranges, plants, etc.

Where can I find Zinc and Copper strips for my science project?

Q: I need zinc and copper for my science project. Which store could i get them from?Thanks.I just didn’t know where to look, that helps!(:

A: dry cells..like d size batteries are enclosed in a zinc can. Just use a saw and cut a d cell open…..scoop out the paste thats inside and wash the outer metal( it’s zinc). Be careful, it’s sharp.for copper you can use house wiring stripping the insulation off. Or, metal shops, hardware stores, etc, should have copper flashing. It is commonly used as an ornament on roofs.
