Homework Help: MOLE Percentage

  1. Nov 6, 2006 #1
    I had this wuestion last week for homework and didnt get the answer because i was not at school today. Any help would be greatly appreciated

    A 12.00g sample of a mixture of KCLO3 and KCL is heated untill all the oxeyen has been removed from the sample. The product, entirely KCL, has a total mass of 9.00g. What is the percentage of KCLO3 in the orignal mixture?

    (The 3 in KCLO3 is a subscript)
