Calculate the number of grams of reactant left over when 28.35 grams of silver reacts with 50.0 liters of air at STP which is 20.9476 % oxygen by volume. The density of air at STP is 1.292 g/L.

attemtp at solution

volume of oxygen= .209476*50L=10.5L

How do i go from volume of oxygen to moles of oxygen the density of air is given not the density of oxygen.
