Carbon tetrachloride or tetrachloromethane (CCl4_4) is a liquid compound that was formerly used as a precursor for refrigerants, as an anti-parasitic agent, or as a component of hard-surface cleaners. However, after the discovery of serious health and environmental dangers associated with CCl4_4 its use is now limited to specialized industrial applications. We learned during the lecture that chlorine atoms naturally occur as a mix of isotopes with relative abundances of: 35^{35}Cl: ≈0.75=75%=3/4\approx 0.75 = 75\% = 3/4 37^{37}Cl: ≈0.25=25%=1/4\approx 0.25 = 25\% = 1/4 What is the probability to find exactly one 37^{37}Cl atoms in a single CCl4_4 molecule?

You perform an experiment that, based on experience from your lab mates, should lead to a success in 2 out of 3 cases. You perform the experiment three times in a row and all experiments fail. Assuming that your lab mates are correct, what is the probability of three consecutively failing experiments?

Following up on the previous question, what is the average kinetic energy of 1 mol of molecules with mass mm at temperature TT? You can make use of the following known integral: ∫0+∞x4⋅e−a⋅x2dx=9π64⋅a5\int_0^{+\infty} x^4 \cdot e^{-a \cdot x^2} dx = \sqrt{\frac{9 \pi}{64 \cdot a^5}}
