Iron pyrite (FeS2) is the form in whichmuch of
the sulfur exists in coal. In the combustion of
coal, oxygen reacts with iron pyrite to produce
iron(III) oxide and sulfur dioxide, which is a
major source of air pollution and a substantial
contributor to acid rain. What mass of Fe2O3
is produced from 70 L of oxygen at 4.12 atm
and 167C with an excess of iron pyrite?
Answer in units of g

    figure the moles of O with ideal gas law.

    n=PV/RT

    take 1/3 of that, that then is the moles of Fe2O3
    calculate the mass of that.
