Iodine–131 is a radioactive isotope that is a by–product of emissions of other radioactive isotopes. After the 2011 earthquake in Japan that damaged several nuclear reactors, high levels of iodine–131 were found near the nuclear power plants. Iodine–131 has a half–life of 8 days. If authorities found an original sample of 2.5 grams right after an emission from the plant, how much iodine–131 would be left 30 days later?0.83 grams 2.08 grams 0.074 grams 0.19 grams
