It really as more to do with your electrical load than the number of oulets.

a 15 amp breaker can will trip after 1800 watts. that could be 20 lamps or one space heater. it depends where the outlets are going.

If you explain what you are trying to do or your problem maybe we can be more help

Your putting 6 outlets in one bedroom? One breaker for one bedroom is very good. if you didnt buy your supplies you can use a 20amp 12 gage wire and be able to run that to more rooms in the future.

To answer the original question, there is NO limit to the number of receptacles on a circuit in a residence.
We just use common sense and take into account the intended use when figuring circuits.

Default good luck DIY

Just make sure you run a 14-2 not a 14-3. All power in a bedroom must be on a arc-fault breaker, and you can not split circuits on arc faults. Commonly I wire 2 bedrooms, lights and plugs on one 15 amp circuit. If you think you might have a laser printer or other office type things, just do only the plugs in one room on a circuit, this will keep load down to accommodate your demand. good luck, and remember we're all pullin' fer ya

There are several manufacturers making two-pole AFCI breakers already, and more will follow. So a multi-wire branch circuit (shared neutral) is no problem with a newer panel.
Old panels and fuse boxes are another story.

A general rule is as follows: Figure 180 VA (watts) per outlet. Using the formula P=IxE P=watts, I=amps and E=volts P=15ampsx120volts=1800VA, now divide 180VA into 1800VA and 10 is the general number that I put on a circuit. This will work the same for a 20 amp circuit as well. I recommend you stay away from a multiwire circuit because it is wired on a double pole circuit breaker and if one side causes a short and trips, the other non affected circuit will trip and thus leaves you in the dark. I teach an Electrical Course and am an active Master Electrician.

Unless you are under the 2008 NEC this is NOT a code requirement.
Also, for relatively newly wired circuit, when was the last time you tripped a breaker?
In being in my (1975) house for the last 15 years, I have NEVER tripped a breaker.
Sorry, I DO NOT buy into that whole "It will leave you in the dark" philosophy.
