Enter your answer in the provided box. Your Answer: Select all that apply. Select two molecular formulas for a molecular ion at m/z = 100. C4H₁2ON C6H12N C₂H15 CsHgO₂ C8H4 C8H5 What is the mass of the molecular ion formed from compounds having the molecular formula, C4H8O? Calculate your answer to the nearest whole number. Enter your answer in the provided box. Your Answer:

22-30. (a) The mean free path is the average distance a molecule travels before colliding with another molecule. The mean free path, A, is given by A = kT/(V20P), where k is Boltzmann’s constant, T is temperature (K), P is pressure (Pa), and o is the collision cross section. For a molecule with a diameter d, the col- lision cross section is nd. The collision cross section is the area swept out by the molecule within which it will strike any other molecule it encounters. The magnetic sector mass spectrometer is maintained at a pressure of ~103 Pa so that ions do not collide with (and deflect) one another as they travel through the mass analyzer. What is the mean free path of a molecule with a diam- eter of 1 nm at 300 K in the mass analyzer?

(5): The pKa of HF is 3.167. What is Kb for F¯ ?

I do not know how to find the molecular formula

(22) 1. NH2 2. AI3 NH2 12 3. NaOH, H,0,A (3) OH. Z.(H9), HCL O KMNO4, NAOH, D

Using the following monomer: H2C CH C CH- CH CH CH C-F (the benzene ring does not react) draw the mechanism for the formation of the polymer, stopping after attaching three units of the monomer together. DETAIL!! You will need more than one reaction, and yes, this will be one time you need to consider the mechanism. (20 pt.)
