A chemical commonly called "dioxin" has been very much in the news in the past few years. (It is the by product of herbicide manufacture and is thought to be quite toxic.) Its formula is C_(12)H_(4)Cl_(4)O_(2). If you have a sample of dirt (28.3 g) that contains 1.0xx10^(-4)% dioxin, how many moles of dioxin are in the dirt sample?
