There are many.
The gravitational mass is the m that you can calculate from Newton's gravitation law:
g=G*m/r^2,
where g is the gravitational acceleration (=gravitational field) caused by m at a distance r, G the universal gravitational constant..
The inertial mass is the m that you can get from Newton's dynamic law:
F=m*a,
where F is the force to be exerted on m in order to accelerate it by a.
The two definitions coincide at low energies, as in everyday life, school lab, and so on. Einstein's general relativity proposes that the two masses are the same in all situations, giving rise to all kinds of distortive effects known as curvature of spacetime.
Careful: the amount of matter is given in moles, and has nothing to do with mass (I made the mistake of confusing the two once =$)! Your teacher should have explained this to you, that's why he wants to know it from you.

anything you see or feel in this universe is mass

In science it's how much matter is in an object.
