SOLVED: This exercise uses the radioactive decay model.Radium-221 has a half-life of 30 seconds. How long will it take for 96% of the sample to decay? (Round your answer to the nearest whole number.) secondsNeed Help?Radioactive DecayMaster [Talk to Tutor /1 POINTSSALGTRIG4 4.6.021.MIMY NOTESThis exercise uses the radioactive decay model.If 250 mg of a radioactive element decays to 190 mg in 12 hours, find the half-life of the element. (Round your answer to the nearest whole number.)
