Subtract the mass of the beaker from the total weight.
No the weight of an object has nothing to do with friction. Weight is the gravitational attraction of the object and the planet.
The weight of an object is the force of gravity.
If the object is floating, then the buoyant force is equal to the object's weight.
The weight of any object on the Moon is about 1/6 of the weight of the same object on the Earth.
Object's weight = (object's mass) multiplied by (acceleration of gravity in the place where the object is)
A gram would be an appropriate measure for its mass.
It is necessary to know the mass of the empty beaker.

Measure out any volume of water in a pre-weighed beaker (or container...sigh*). Then bake the beaker in a warm oven until all the water evaporates and the beaker is dry. Reweigh the beaker . Subtract the original weight of the empty beaker from the new weight. You now have the weight of the salt present in your original amount of water ! NOTE: If you are using ocean water this may be imprecise due to other contaminants remaining in the beaker. AKA you are not JUST weighing salt at the end.

Scale.
The weight of an object is the force of gravity.
Zero.
The mass of an object does not change , but its weight can vary.
If the object is floating, then the buoyant force is equal to the object's weight.
If the object is floating, then the buoyant force is equal to the object's weight.
The weight of any object on the Moon is about 1/6 of the weight of the same object on the Earth.
The water around floating object's is a measure of that object's "Displacement". For the object to float the weight of displacement must equal the object's weight. If the water around an object is of a greater weight than an object's displacement, then the object will sink.
