Completely dependent on the specific part in question. Digital accelerometers are in the range of 8 to 12 bits ( a couple thousandths of a g per count), but you can buy better or worse. Really what kills you is part to part variability - you can easily get 20% sensitivity variability and/or offset variability, so be sure to calibrate if you need to. Also, some of them are really temperature dependent.
