hi
oxygen is a diatomic molecule =o2= (16*2)=32g in one mole
so as we know that 32g of o2=1 mol =6.023*10^23 therefore
320mg=0.32g=0.01mol=6.023*10^21 from this ,6.023*10^20 moles are removed =0.001 moles and
therefore remaining moles are 0.01-0.001=0.009 moles remain
hope this information is usefull
all the best
