a laboratory has a 75 gram sample of radioactive material that have live with a material is 10 days this means that it takes 10 days for half of the initial Mass to Decay formula below can be used to find M the remaining mass in grams in term of T the number of 10 day intervals the mass has been a m equals 75 * 0.5 T based on the formula what is the mass of the Laboratories sample remaining after 30 days
