A particular radioactive isotope has a decay rate of -0.173% where time is measured in years. A scientist started with 1,490 milligrams of this material. Use the Continuous Decay Formula: F=Pert to find how much of the material will exist in 640 years?
milligrams Round answer to the nearest tenth of a mg.
What is the Formula that will convert a Continuous rate (r) into a Halving factor (H)?
What is the Half Life of this radioactive isotope?
years Round answer to the nearest whole number.
