tritium has a half life of 24.3 years .a sample of 0.1 is produced . will tthe mass of tritium change after 24.3 years

To determine whether the mass of tritium will change after 24.3 years, we need to understand the concept of half-life. The half-life of a radioactive element is the time it takes for half of the sample to decay.

In this case, tritium has a half-life of 24.3 years. This means that after 24.3 years, half of the tritium sample will have decayed into another element.

Now, if you start with a sample of 0.1 grams of tritium, after 24.3 years, half of that tritium will have decayed. This means that you will have 0.1 grams divided by 2, which is 0.05 grams of tritium remaining.

Therefore, the mass of tritium will change after 24.3 years. It will decrease from 0.1 grams to 0.05 grams due to radioactive decay.
