there isnt any way to determine how much a snake should weigh. the genetics and metabolism of each snake will determine that, although imo, 182g at a year does sound pretty low. all you can do is put them on a proper feeding schedule with the appropriate prey size (10-15% of snakes body weight) and see how fast they pack on weight. and then you might be able to determine how much they should weigh at future points of age (maybe).
whats your feeding schedule for your female, and how long have you had her?
how does she feel, mushy, firm, does she flatten out alot?
