Sorry to hear that -- well, glad you're getting treatment, but sorry to hear you need it.
The main lifestyle risk factor for gall bladder stones is being obese -- which you clearly aren't - -so probably you've just been very unlucky. Oral contraceptives are also a risk factor, something to maybe discuss with a doctor.
The gall bladder is oblate shaped, and in adults only about 12 cm long (less than 5 inches). You'll have to ask to see the stones afterwards; they may weigh as much as the gall bladder left behind.
Treating it as a sack of water, a 5 inch diameter gall bladder wouldn't weigh more than about 14 fluid ounces (400g). Ask your surgeon, but I imagine 320-400 grams is about right.
