By doing a literature search, state the approximate number of collisions that a perfect gas molecule (e.g. N2) makes at room temperature and at 1 atm pressure in 1 second (you do not need to calculate this value). What is the significance of this value in the experiment of diffusion of gases( the purpose of the experiment is to measure rates of diffusion of two gases through the air as an experimental test of Graham`s law)?

9.79. Suppose we keep drawing cards from a deck of 52 cards with replacement until we see two face cards (Jack, Queen, or King) or two number cards (ranks one through ten).
1. What is the sample space of this experiment?
2. What is the probability function?
3. What is the probability that the experiment ends with two face cards?

The burner head in the atomic absorption experiment was perfectly aligned with the line of view of the detector (compare to tilting the burner head during the atomic emission experiment). If the burner head was left tilted, how would (1) the sensitivity of your calibration method and (2) the random error in the calculated concentrations of the unknown be affected? (i.e. think what would be affected in your calibration curve)?
