analytical balance weighs mass right? but can someone use it while in orbit where there is no gravity and everything is floating?

Without gravity, be it man made or natural. The scales would be useless. Newtons second law of motion is that with every action there is an equal and opposite reaction. Kind of like when you step on a scale, gravity pulls you down while the springs in it record your weight and display it to you. You must have something to counteract the zero g environment for the scales to work.

Balances and scales we developed and can only be used with gravity or under a centrifugal force. It is a measurement of the force a certain mass exerts in the presence of gravity, kind of a useless thing when you think about it.

Yes, but only if a system of artificial gravity was in place. Early Si-Fi films showed space stations designed like a big wheel which rotated around a central axis. This rotation caused "centrifugal force" which acted as an artificial gravity. In that case you would get relative weight, but you wouldn't get accurate mass unless the artificial gravity was equivalent to one g.

probable through relative uncertainty. The gas weighed an extremely small quantity, and the centigram stability had too great an uncertainty to diploma the gas with any precision. The mass of the approximately 50 ml of water could desire to be weighed with adequate precision for a lab test on the centigram stability. The smaller the dimensions, the greater precise the measuring gadget must be. Weighing the water on the analytical stability might have generated significant digits which could have been discarded in the subsequent calculations.

No, scales of any kind are useless in free fall.

ya we can but answer is weight of that object is massless coz of no gravity.
