A Radioactive Isotope Is Released into the Air as an Industrial

question 4

Short Answer

A radioactive isotope is released into the air as an industrial by-product. This isotope is not very stable due to radioactive decay. Two-thirds of the original radioactive material loses its radioactivity after each month. If 11 grams of this isotope are released into the atmosphere at the end of the first and every subsequent month, how many grams radioactive material are in the atmosphere at the end of the twelfth month? Round to 1 decimal place.
