how much solder & flux

So, I'm gonna sweat some lead free ball valves, (6) 3/4 inch and (7) 1/2 inch. Do you think a 1 pound spool of solder and an 8 oz can of flux are enough?
Thanks

The other thing that i was taught, how much solder do i use because some people over solder. What works for me is, if it is a 1/2 inch pipe i use 1/2 inch of solder, 3/4 inch pipe 3/4 inch solder and so on.

Practice makes perfect. If you're new to this, then most likely you'll over solder and even have heavy drips. But that is not a problem. The important this is not t wipe off over solder. Common mistake by many. Let it cool by itself. If disturbed you'll get "cold" solder. This is more critical in electrical work, but in plumbing it can cause a weak joint and eventual failure.
