Answer 1

Mass:

If you could count up the number of protons, neutrons, and electrons in an object (which you probably can't), this would be a measure of the mass. The mass is essentially "how much stuff" is in an object.

weight:

There is a gravitational interaction between objects that have mass. If you consider an object interacting with the Earth, this force is called the weight. The unit for weight is the Newton (same as for any other force).
