ok i need to find how many atoms thick a zinc coating is on a galvanized steel washer. i have found out that there is a total of 1.105X10^21 atoms overall in the washer of zinc. the density of zince is .5712??? any ideas for how i can find the answer

Your question is not clear, and there appears to be missing information. You referred to a galvanized STEEL washer. Then you say there are 1.105x10^21 atoms in the "washer of zinc". But the washer is steel. Do you mean there are 1.105x10^21 atoms of zinc on the steel washer? There is still not enough information unless we know the size (dimensions) of the washer. I don't see where in your data we can deduce the size or surface area of the washer.
