Homework Help: How to start this off ( chem ?)

  1. Jan 27, 2008 #1
    in order to plate a steel part that has a surface area of 200 in^2 with a 0.002 in thick layer of nickle, how many atoms of nickle are required

    not looking for an answer i just need help on what to do. i know how to find how many atoms of somthing when given the weight. just not sure what to do in this case. i was thinking find the volume by 200 * 0.002 then using the density of nickle to find the mass and then go from there. But the numbers i was getting didt seem right.

    Your approach looks correct. Can you show us the calculations?
