Consider the following statements as they apply to mass spectrometry. Decide if each is true or false.

True False  It is possible to get a mass spectrum of large analytes like polymers and biomolecules because of the development of ionization techniques such as MALDI and FAB.
True False  For a particular analyte, the mass spectrum obtained is highly dependent upon the ionization technique used.
True False  Though a gas chromatograph (GC) is a common way to introduce a sample into a mass spectrometer, a liquid chromatograph (LC) is never used for this purpose.
True False  A mass spectrometer is an instrument that produces ions and separates them according to their mass to charge ratios, m/z.
True False  The nominal mass of an ion is calculated by summing up the atomic masses of the most abundant isotopes.

P.S. the answer is not F, T, F, T, F - please do not answer if you do not know I have one attempt left for this homework

Decide which of the following statements are true and which are false, concerning the kinetic molecular theory. 1. The particles are assumed to exert no forces on each other; they are assumed neither to attract nor to repel each other. 2. The molecules in a real gas have finite volumes and do exert forces on each other, thus real gases do not conform to some of the assumptions of an ideal gas as stated by the kinetic molecular theory. 3....
