Is the amount of substance in a certain volume the pressure?
No, the pressure is the force exerted by the substance on the walls of its container. The word that comes to mind for "amount of substance in a certain volume" is concentration, though it might also be a somewhat awkward way of describing density.The amount of substance in a certain volume is the density of the substance. Pressure means the force applied in a unit area. So the amount of substance in a certain volume is not the pressure.

The separation of petroleum into components based on their boiling points is accomplished by?
the answer is fractional distillation because there are many different substances in the crude oil. each of them has different melting points, boiling points, freezing points and so on (different physical properties). therefore, if you heat them up, each of them may evaporate at a different temperature. you can then collect the oil substance if you can control the temperature at a certain range. cracking and melting are used for solid substance, not liquid based polymerization is a chemical reaction, which will not help you separate the matters.
What does a mole measure?
An instrument can not be used to measure moles because moles is the amount of grams of a substance divided by the molar mass of the substance. This can not be measured and has to be calculated.

The smallest such substance is a molecule, or a formula unit of an ionically bonded compound. Any amount of such a substance also satisfies the requirement given.
Is the molar mass a fixed quantity for a particular substance?
For most purposes, the molar mass of any particular substance remains the same. However to be precise I will note that there are isotopic variations which can affect molar mass. In other words, it is normally expected that a given substance will have a certain mixture of isotopes giving a certain mass, but a substance obtained from one source might have a different isotope ratio than the same substance obtained from a different source.
