If you're starting out generally:
8-10: shoulders (small muscle group)
7-9: biceps (small muscle grup, short workout)
10-15 back (large muscle group)
10-12 chest
10-15 legs
8-10 Triceps
That's higher than many guys on this forum will advise, however most people here are more experienced lifters and can get more out of less. I'm not saying that high volume is good for starters (and this certainly isn't HIGH volume) but you need to develop the mind-muscle connection.
As you get the hang of really isolating the intended muscle group and getting as much power as you can out of it, then you can adjust the volume accordingly.
You can (and should) do abs, but their schedule depends on the person. I usually work abs three days a week, but some people go as high as everyday. If you're more of a bodybuilder that would be fine, but if you're looking to get sheer power and doing a lot of the primary compound lifts (deads, squats, bench) I recommend a little less. For Deads and squats, lower back and abs play a HUGE role and it would be uncomfortable and maybe even dangerous to do heavy squats with abs that were weak from a different workout.
Forearms and Calves should also be trained, but they can be beat on pretty heavily. I don't even train calves since I get enough stimulation from squats and running to keep them in good shape. Forearms I absolutely hate to train and do with biceps. Doing wrist curls to failure makes me want to vomit it burns so badly.
