The word weight in every day speech means how much do you weigh converted back to mass. That is if I ask "what do you weigh?" but I want the answer in pounds or kilograms.
In science mass is measured in kilograms (or pounds outside the science lab) but weight has more to do with the gravitational pull of the Earth.
Newton's second law is F = ma
Force = mass x acceleration
Weight = mass x acceleration due to gravity
W = 50 kg x 9.8 m/s2 (Force or Weight has a unit of Newtons, N)
= 490 N
Why? Perhaps because when we use the balance or the weighing machine we are using gravity but then we convert the scale back to mass.
Mass is how much matter is in an object and weight is how much force of gravity is pulling an object.
Weight is not a physical property of an object, it is an effect, which varies from place to place. A given object will have the same mass no matter whether it is on the Earth, or on Mars, or somewhere in between.
They use a tri beam scale.
The units grams would be a good choice.
Sure, you can use a balance scale instead.
Weight-hangers are used to add desired amounts of weight to create the mass needed. The mass created is used for experiments involving mass, acceleration and force.

No. Mass is the weight of an object on earth. Scientists use mass instead of weight so the measurements will be the same everywhere. For example A big ballon has a relatively lower mass than a small sized stone
yes
Mass doesn't change where ever the object or thing is but weight changes depending on where it is(depends on acceleration due to gravity-g) Eg: Mass of object doesn't change either it is on moon or earth but weight changes(on moon it is 1/6 of that on earth).
The percentage of each isotope is different.

The mass is a measure of the amount of matter present in an object whereas weight is a measure of the force on the object due to gravity. Weight is measured in Newtons, mass is measured in kilograms (pounds in the Imperial system) When we use the term weight outside of science we actually are referring to mass. mass is a measure of 'stuff,' of material that makes up an object. weight is the gravities affect on mass as you can see from the equation Fg=mg, m=mass g=gravity (on earth it is 9.8) and fg is weight in newtons
mass
You use the formula weight = mass x gravity. In SI units, the gravity is 9.8 meters per second square, weight is in Newtons, mass is in kilograms.You use the formula weight = mass x gravity.

A Scientist would use a balance, either triple-beam or electronic.
Use the advanced search tool and search on weight and mass.
