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.
Did you read my response to this question last night? If so, what's the problem?
