thallium-201 73

sodium-24 15

rhodium-105 35

Based on the table, which of these conclusions is most likely correct?

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.
