How to solve half life problems
WebJun 21, 2024 · To solve word problems involving half-life, time, and mass of a radioactive substance. Whether or not a given isotope is radioactive is a characteristic of that particular isotope. Some isotopes are stable indefinitely, while others are radioactive and decay through a characteristic form of emission. As time passes, less and less of the ... WebI can do this by working from the definition of "half-life": in the given amount of time (in this case, 9.45 minutes), half of the initial amount will be gone. That is, from t = 0 to t = 9.45 , I will have gone from 100% (" 1 ") of however much I started with to 50% of that amount (converted to 0.5 for use inside the formula).
