A copper ore consists of 6.32% chalcopyrite, CuFeS2(s). How many grams of ore must be processed to obtain one gram of copper?

  • Chemistry -

    Just substitute into what you know. What is percent?
    %Cu = (grams Cu/grams ore)*100 =
    You know %Cu, you know grams Cu you want, solve for grams ore needed.

  • Chemistry -

    The above is incorrect and finds ratio chalcopyrite to ore. Not Cu to ore.
