Mass is a fundamental concept. Amount of matter is mass. But what is matter?Generally it is referred as the mass of a body that is the amount of matter included in a body.
A body is composed of atoms and molecules. Atoms and molecules are composed of electrons, protons, neutrons and a number of fundamental particals, We do not know exactly how many fundamental partciles exist, what is their nature, what they are composed of etc.
Finally we reach what is the least quantum of matter? It is a mind boggling question.
Now it is conceived that the fundamental particles are the condensed forms of energy and the quantum of energy is a `string` and this concept is known as `String Theory`
So mass is nothing but the amount of energy in the condesed form. Interesting...isnt it?
Again the problem remains, how to deal with different quantities of mass? then the concept of weight comes in. It is the amount of force generated by the gravity of Earth. Since the magnitude of the earth`s force ...more

weight= mass X gravity ie W=mg.

see mass is weight only(in lay man langugae)
but in physics weight is said be as force
so it is w= m*a or g
g is gravity or acc.
m is mass
n w is weight
but S.I unit for both is same

mass is a measure of how much matter an object has. weight is a measure of how strongly gravity pulls on that matter. thus if you were to travel to the moon your weight would change because the pull of gravity is weaker there than on Earth but, your mass would stay the same because you are still made up of the same amount of matter.

W = Mg
Weight is a vector quantity.
Mass is a scalar one and has no direction.
Mass is constant but weight is relative. Our mass will be same on moon or on earth but weight will differ depending upon the value of "g".

MASS---------->>VOLUME X DENSITY
WEIGHT------->>MASS X ACCELERATION ( OR ) MASS OF A BODY X GRAVITATIONAL FORCE

Well mass is the same no matter what planet, and weight is a measure of gravity. Wat ur teacher said is true...in America, we use the pound, which is strictly for weight, while for weight in other countries they use the gram, which is actually a measurement of mass. To mass something, you must use a balance scale.(I know, it's confusing isn't it?)
