Strictly speaking no. For practical purposes yes.
Mass does not change - 1 kg is 1 kg anywhere in the universe. However, 1 kg weighs less on the moon than it does on the earth. Weight is dependent on gravity.
1 kg weighs 9.81 Newtons on the earth and about 1.64 Newtons on the moon.

FranNo, mass and weight are not the same thing. Mass is a measure of the amount of matter in an object and remains the same regardless of the gravity acting on it. Weight, on the other hand, is a measure of the force of gravity acting on an object and can vary depending on the gravitational field strength.
No it is not. Mass is a totally different thing in science than weight.
Mass is the amount of matter that an object has. Typically expressed in kilograms, mass can be calculated from the force applied to an object and the acceleration that the object experiences because of that force. The equation is f = ma, where f is force in Newtons, m is mass in kilograms, and a is acceleration in meters per second squared.
Weight, on the other hand, is the force that the object experiences due to acceleration due to gravity. The equation is still f = ma, but (typically, on the Earth) a is 9.81 meters per second squared.
Now, if you want to be technically accurate, that means that an object with mass of 1 kilogram weighs, on the Earth, about 9.81 Newtons. We have a tendency, however, to state weight in kilograms also, so we would tend to say that the object has weight of 1 kilogram. The agreed assumption in that case, is to normalize to the effect of gravity and divide Newtons by 9.81.
This won't work anywhere else, of course, such as on the Moon. The Moon's gravity is about 0.17 of Earth, so that same 1 kilogram (and I do mean mass, here) object would weigh about 1.64 Newtons.
Note very importantly, that the object still has mass of 1 kilogram, and it will still take the same amount of force to accelerate it by the same rate.

Is it true your mass on earth is the same on the moon?
Yes. Your mass never changes, no matter where you go but your weight can be affected by gravity.
What is the one thing that remains the same no matter where you are on earth?
The force of gravity remains constant no matter where you are on Earth.
Does everything have definite mass?
Yes, everything in the universe has mass, which is the amount of matter an object contains. However, some mass may be very small, such as the mass of individual subatomic particles.
Do all rocks weigh the same if they have a different mass but the same weight?
No, all rocks will not weigh the same even if they have different masses but the same weight. Weight is the effect of gravity on an object, while mass is the amount of matter in an object. Therefore, two rocks with different masses but the same weight will not weigh the same.
Will your mass be the same on Pluto and on earth?
Yes. Mass is a measure of matter. If you were to go to Pluto, you would still have the matter that you're made up of. The difference in the gravitational force of Pluto and that of Earth would affect your weight, but not your mass.
