The first step in the process used to recover zinc metal from zinc sulfide ore is the reaction of zinc sulfide with oxygen gas to produce zinc oxide and sulfur dioxide.
2 ZnS(s) + 3 O2(g) → 2 ZnO(s) + 2 SO2(g)
When the external pressure is 142700 Pa and the temperature is 689 K, the amount of work performed is 879.1 J. Calculate how many grams of oxygen are consumed in the reaction. i'm not sure how to solve it. Thanks

Dr Bob can you please help me? I'm stuck on how to convert to grams from moles. I used w=PV rearranged it to w/P=V and changed the volume from mL to L. Then I used ideal gas law PV=nRT to find n=moles. Also do i need to convert external pressure Pa to atm when i use PV=nRT to calculate for moles?
