once all the liquid is gone and only vapor remains you can calculate how much is left using pressure and the temp of bottle.

I want to know if it's damn near empty now or there is a few pounds in there,I want to know if I have enough to trim in my system,or do I have to get a new bottle.

you can either hook it up to your suction line and use your compressor and close the liquid line to pump down the cylinder until satisfied or you can call Du Pont and ask for net weight when empty

R410A cylinders average 9 pounds. They have no tare weight stamp on them.
