Half-life of heavy hydrogen: This is a continuation . We stated that the half-life of a radioactive substance does not depend on the initial amount. Using the information from , show that it takes the same amount of time for 100 grams of heavy hydrogen to decay to 50 grams as for 50 grams to decay to 25 grams. How long will it take for 100 grams of heavy hydrogen to decay to 6.25 grams? (Note: You can do this without your calculator!)
