CAN YOU PLEASE SOLVE 2,3,4 PART PLEASE ASAP I WILL RATE THE ANSWER...
What mass of a 2,400g sample of an isotope will remain after 32.8 days if the half life of the isotope is 8.2 days? A 640g sample of an isotope decays to 40g in 625minutes. Find the half-life of the isotope. A sample contains 9,000 particles of the original isotope for every 63,000 particles of the daughter isotope. The half-life of the original isotope is 19 years. Find the age of the sample. A 416 g sample of sodium-24 decays to 13.0 g of sodium-24 within 60.0 hours. What is the half-life of this radioactive isotope?
