Cаrbоn tetrаchlоride оr tetrаchloromethane (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%=3/4approx 0.75 = 75% = 3/4 37^{37}Cl: ≈0.25=25%=1/4approx 0.25 = 25% = 1/4 What is the probability to find exactly one 37^{37}Cl atoms in a single CCl4_4 molecule?
