A scientist kept 1,000 gram samples of radioactive thallium, sodium, and rhodium in three different containers. The table below shows the half-lives of the Radioactive Material
Half-life (in hours)
73
thallium-201
sodium-24
rhodium-105
15
35
Based on the table, which of these conclusions is most likely correct? (1 point)
After 45 hours, the amount of sodium left in the container will be 125 gram.
After 45 hours, the amount of sodium left in the container will be 250 gram.
After 70 hours, approximately 500 gram of thallium and rhodium will be left in the containers.
After 70 hours, approximately 125 gram of thallium and rhodium will be left in the containers.
