What would cause the water in the toilet tank to drain out completely?
There isn't any outside leak. Would it be the gasket at the bottom of the
ballcock? I put in a new ballcock thinking that this was the problem but
the water is still draining out. Any suggestions would be appreciated.

I'll try again. Right, this is an emty tank; not bowl!
Check the flapper - does it leak?
Does the ballcock turn on the water when you lower the ball? It should.
There may be a clog/plug in the pipe, or the inlet valve itself is
defective.
