Best Answer

The amount of material left in radioactive decay is an exponential function. Therefore, the way you solve this is to write it as an exponential function; for example:

f = e-kt, where "f" is the fraction remaining after a certain time, "t" is the time in any unit you choose (for example, years), and "k" is a constant you have to find out. Replace the numbers you know (for t = 1600 years, f = 1/2, since 1/2 of the original remains), and solve for "k".

Then, write the equation again, this time with the constant "k" you figured out before, and the time (365 years). This will give you the fraction left after that amount of time.

If Ra-226 had a f life of 1600 years and you have 20 grams how much will be left in 3200 years?

I will try to make the answer simple for you. Half life is 1600 years. So After 1600 years you have half the mass left. That is 10 grams. After another 1600 years, you will be left with half the mass of 10 grams. That is five grams. So after total 3200 years you will be left with 5 grams of mass of the Ra-226 left with.


How many grams of radium-226 will remain from 5 grams after 365 years if the half life of radium 226 is 1600?

The question, as posed cannot be answered because you have not stated the units for the half-life. Some things have half lives of millions of years while others have half-lives measured in micro-seconds. Fortunately, Wikipedia came to my rescue and the half-life is 1600 years (approx). The answer is approx 4.3 grams.
