CF2Cl2 is a chlorofluorocarbon (CFC) that has been tied to the destruction of the atmospheric ozone layer. In the year 2000, it reached a peak concentration of 2.2 x 10-11 M in the atmosphere. The destruction of CF2Cl2 can be approximated as a first-order process and the 1996 treaty on CFC emissions has eliminated its release into the atmosphere. Since the half-life of CF2Cl2 in the atmosphere is 77 years, how long will it take for the concentration of CF2Cl2 to decline to one-quarter (25%) of its concentration in 2000? (Note that one-quarter of its year 2000 concentration is 0.55 x 10-11 M.)
