1) the molar mass of an element is found on the periodic table. It is often referred to as the mass number.

2) the molar mass of a compound is the sum of the molar masses of its elements. Don't forget that if there's two of an element in the compound, you must multiply that element's molar mass by two.

3) You can only find the amount of protons and electrons given atomic number. They are both equal to the atomic number. To find the amount of neutrons, you need the mass number as well. The amount of neutrons = mass number - atomic number.

4) I'm not sure about kinetic theory. I think it might say that everything's always moving. Particles in solids move slower than those in liquids which move slower than those in gasses. Not sure what else.
