Subject: Will a air tank with the air removed from it float in water?

If an air tank filled with the normal atmospheric pressure of air can float 
would it sink if it were filled with one hundred pounds of air or more? I’m 
thinking that it may very well do that sent air has weight. Take that same air 
tank and remove all the air from it, will it sink or will it float? This is a 
question I’m not sure about. I’m thinking that sent it has no air in it; it 
will sink because it has nothing to keep it a float. Can someone please help 
me with this question?
